Learn how to create a striking spliced paradox cane out of polymer clay:

Some common steps (e.g. skinner blends) are covered only briefly, but here’s some resources that may help with those skills:


Clay recipes (Kato):

  • Violet: 1 part Magenta, 2 parts Purple
  • Sea Green: 1 part Turquoise, 2 parts Green

Five critical steps:

  1. Reduce and reshape by squeezing the middle — not the ends
  2. Make sure the long back side is well-joined so it doesn’t split later
  3. Re-shape the cane components to a curved “J” shape, not an “L” shape
  4. Always keep corners and edges sharp
  5. Take your time reshaping and arranging the final pieces

See how to cover a cheap pen with an existing triangle cane and finish it smoothly and beautifully to create a professional pen without any extra tools or supplies. No lathe, no pen press, no pen kits — just a cheap pen, a triangle cane, and the tools you already use to make and finish your other clay projects.

I know everyone isn’t as interested in making a zillion pens as I am, so many won’t want to buy dedicated hardware. I wanted to see if I could take what I’ve learned with higher end pens and apply it to a fifty cent disposable pen and still get a great result.

(No cane-making in this video, just covering a pen and how to get a professional finish on it.)

59 minutes:

• 1 minute for disassembly
• 38 minutes to cover the barrel
• 8 minutes to flatten and smooth
• 11 minutes for sand and polish
• 1 minute for assembly

Brush Cane Video Tutorial

My very first video tutorial! If you’d like to see more, please subscribe to my YouTube channel: https://www.youtube.com/channel/UCbut4v30Fv–I_qF3GHmsKw/

In this video, you learn how to make an organic-looking polymer clay cane that imitates a brush stroke of oil paint, and cover a pen barrel with it.

I spent a while trying to come up with a way to make a polymer clay cane that looked like a brush stroke of oil paint, and am very pleased with the result. There’s no special equipment required, although I found it works much better with this wavy vegetable cutter that you can get cheaply on Amazon: https://www.amazon.com/gp/product/B0001XXCYC

Spliced Paradox Cane Tutorial

I am now making video tutorials also: my channel is at https://www.youtube.com/channel/UCbut4v30Fv–I_qF3GHmsKw/

Video version of this written tutorial:

This tutorial shows two different ways to arrange the colors in this cane to create two different looks. Below, in the third picture, I also include a third option where you combine both canes alternating to create an additional arrangement.

I really love the “paradox cane” for fun visuals. The first time I saw it, it was a set of rough pictures from Vivid Clay with a bit of explanation: here’s her tutorial from January 2018. The first full tutorial I saw was from Meg Newberg: Polymer Clay Paradox Cane Tutorial in December 2018. There have been many variations made, and it’s a pattern you can find in Op-art. This variation here is mine, combining a basic spliced cane with the construction of the paradox cane.

There are multiple ways to make this cane “yours” and I note them along the way, but here’s a summary:

  • Choose different colors
  • Make messier or cleaner slices in the jellyroll
  • Change how much you do/don’t modify the jellyroll pieces
  • Change how much the colors overlap when you assemble the cane
  • Cut the jellyroll into more pieces or duplicate the cane and turn it into a square again before transforming it into a triangle

At the end I have a small gallery of various ways of doing a paradox cane, varying how the blends are done and how it’s constructed.

This is not a tutorial for complete beginners, as I am not explaining how to do basics like skinner blends and jellyroll canes, but there are many videos on YouTube explaining these basics, so don’t hesitate to check them out.

Materials

  • Equal amounts of two sets of matching colors that contrast with each other; for example, blue/green and yellow/orange
  • Double that amount of white (half for one blend, half for the other)
  • Clay slicer
  • Roller or pasta machine for making blends

Choose colors

Pick two sets of colors that go well together, but where the whole set contrasts well. I went with a blue and a green (and dulled versions of both colors) and orange and yellow (I wanted them bright so used the base kato colors for those.) If you use Kato and want to replicate my colors exactly, I used my recipes for Antwerp Blue and Cossack Green.

Technically you could have the third color be black instead of white, but I’d recommend white. At a small scale, black can really darken the pattern if you aren’t careful, and it’s easy for everything to look duller than you intend.

If you’re just wanting to experiment, I wouldn’t use more than ~15g of each color. When I made this set of canes I actually used 60g of each color and then split each blend in half since I was making two canes, so you’ll see a lot more clay in my blends below than is strictly necessary.

Skinner Blend

You could do this with just two colors and a straight half-and-half blend, but I wanted a bit more complexity for when I was using my canes to make bowls where you can see more details of the canes. I used about the same amount of each color and arranged them as shown here in the picture.

Absolute precision isn’t required, but don’t be too far off or the blend may not be as smooth as you want.

I chose to have some solid on both ends (about half an each on each end, out of a 6.5 inch wide blend) since you can always trim it off at the end if you don’t want that much of the two end colors.

Jellyroll both colors

You don’t actually need two of each, I just did that to be able to make both color arrangements of the cane to be able to show what both look like.

Slice each jellyroll

While perfect precision isn’t important here (and in fact, some variation adds to the organic effect) I still like to use guides.

First I slightly flatten the jellyroll to make it a bit easier to score the top and bottom consistently with the blunt side of my blade. Then I connect those two indentations along the sides to create a guide for where I want my blade to go.

To cut following the guides, rock your blade back and forth so you can watch each side one at a time and not get too far off course.

When you’re done, you will have cut each jellyroll into four pieces, and one of the pieces in half in one of the jellyrolls. One jellyroll will be in four pieces and the other in five. The one you cut into five pieces (three quarter-pieces and two eight-pieces) will go on the outside of your cane.

In my picture below I have twice as many canes because I made both combinations. I chose to pick a different color to cut in half for each cane. I’ll explain why later.

Modify the pieces (Optional)

I wanted a bit more painterly look, with the colors bleeding around a bit more, so adjusted each individual jellyroll piece slightly by pulling the dark outside up towards the white.

I didn’t just squeeze them, I pulled the sides up a bit. You can see a comparison in the last two pictures below: the modified piece is on the left, and the unmodified piece is on the right.

You can choose to skip this, or pull it up higher if you want even more contrast deeper into the middle of the cane.

Assemble the pieces and reduce

Arrange your pieces alternating by color, putting the two smallest pieces on the outsides of the cane. If you are only making one version of this cane you will only have one of the two made.

The more the pieces overlap the more intermingling of colors there will be at the end. The less they overlap, the more the middle of the cane will just be white/pastels. Both are nice, it’s just which you prefer. I chose more overlap since I wanted the colors intermingled.

Then reduce it down to approximately a square. Precision isn’t critical here.

You don’t want the cane especially long here though — as you can see measuring against my fingers, as I shortened it on the long side I made it longer on the short side. The cane’s depth didn’t change much at all, to make the next few steps easier.

One mistake I made here that made future steps tougher is I didn’t do a good job of really combining the top and bottom of the cane where the jellyroll pieces of the same color come together. Later when I tried to turn it into a paradox cane those end bumps kept coming apart and breaking. I’d recommend spending the time to really combine the top and bottom along the depth of the cane and make them as smooth as you can.

You also have an option here to cut it in half, put the two side by side, and transform it into a square again. This will give you more pointy bits and more detail in the final cane. I didn’t do that because at the small size of a pen, I felt it would make the design too muddy. But it’s something to consider if you’re using this cane for something larger like jewelry, a bowl, or covering something.

Transform the shape

Next you want to take your cane into a triangle — and here’s where I made a small mistake. My intent had been that the major central color would be the one that had those little eight-pieces, so that where it met in the middle you’d have a mirror of that major color rather than a gap. But I reduced the wrong side of the triangle.

Ultimately I’m not sure it was that big a deal, but I wanted to note it in case you prefer to try what I’d originally intended. In that case, where you see me squeezing the orange (which in this cane was the jellyroll in four pieces) you would want to reduce the blue (the one in five pieces.)

A critical note on the transformation: you want to squeeze from the center rather than just the end, and carefully work it into a triangle. If you just squeeze the end together, your outer two pieces will come together and the middle ones will end towards the middle rather than coming to a point along with the outer pieces. If you like that look, great, do it! But I preferred to have all the pieces coming together as much as possible.

The cane will grow a bit in length here, I just kept pushing it back. The other thing you want to do is widen the side you aren’t squeezing together, as you’ll need to pull it up in the next step.. It’s okay if your triangle isn’t shaped exactly like mine, there’s still a lot of reshaping to go.

Make a J shape

This is the second-hardest step.

You want to carefully and as evenly as possible thin out one end of the triangle and curl it over. To get the best effect, you want to get all the clay moving, not just the very tip, so it all curls up and around. So similar to before, you can see me putting pressure nearer the middle of the cane with my thumb rather than just the tip of the cane.

You also really want it to curl around — even more than I did here (remember what I said above about not smoothing that blue edge enough? It was causing problems in this step so I didn’t get it curled over enough.)

It helps to have a barrel of some sort to curl it around — I used an unfinished pen tube but you could use anything.

It will make your next few steps easier if you crisp the edges of the cane — even more than I did. Pinch in all three corners.

You can see in the last picture the breaking I spoke about a few times earlier in the dark blue back of the cane on the right. Avoid that by fixing it when you are squaring the original cane, it really helps a lot later!

If you are working with Kato I specifically recommend not letting the cane rest before the next step — more pliable helps a lot. These cane shapes aren’t quite right, and you’ll end up wanting to reshape them a bit when you try to assemble.

Assemble the paradox cane

This is the hardest step and I suspect where folks tend to get stuck on this cane. I’ll do my best, but a lot of it is just practice, and having your cane shapes right (having a good ‘J’ shape, not having the backs break, and paying attention to my pictures below will help.)

If you haven’t done it before, consider buying Meg’s tutorial, Polymer Clay Paradox Cane Tutorial, for more help on the final construction of the cane.

And as noted in the step above, if you are working with Kato I specifically recommend not letting the cane rest before this next step — Having it be more pliable helps a lot.

The first picture and second pictures show the idea of how the pieces go together — but the second you try to add a third, it’s hard to see how it will ever close into a triangle (see the third picture.)

Here’s some tips I’ve followed when trying to assemble paradox canes.

  • It’s okay to stop and re-shape your pieces before continuing. Look at the shape in the final pictures and see how long I had to make the orange part of the triangles to fit.
  • It’s going to pop apart a million times — that’s okay. Just keep working around in a circle, stretching and shaping the clay making a little progress each time
  • The middle gets messy: and it can be hard to fully pull the pieces back apart midway, so I try to get my middle lined up well from the start (2nd picture above) and then get the 3rd piece into that curve as well, and focus on getting the backs to be shaped right
  • Be careful about the points of your final triangle: ideally the orange and blue should meet exactly at the point. It’s very easy to not get the long thin color (orange above) to the point, and I don’t think the final result looks nearly as good.

In the first picture below you can see how the orange and blue both come to each point in the triangle.

And Finally, it’s never going to look perfectly. And that’s okay, because with this cane much of the magic happens between the slices when you tile them. Here’s the quick test I did with a pair of mirrors to show how each cane kaleidoscopes.

While you spend so much attention during assembly on that swirling middle, those details become background and just a swirl of color supporting the main pattern.

More examples of paradox canes

This basic construction method can be used to produce a variety of different effects depending on whether you use one color, two colors, mirror your blend, etc. Here are some more examples of work I’ve done.

Cleaning CA Glue off your bushings

I don’t know why this was so hard to get information on when I first started, but it was! So writing a short post dedicated to the topic.

Whether you use non-stick bushings or not, you will end up with CA glue all over your bushings — the main point of the non-stick bushings it to make it easy to get the bushings off your CA-finished pen, rather than to prevent it from fully sticking to the bushings.

Applying wax to the bushings ahead of time can help your pen separate after finishing (I use a caranuba wax, though I suspect any will work), but there’s still the question of getting the CA glue off the bushings after it builds up.

I have a bottle of pure acetone and several sets of non-stick bushings. After enough of them get enough CA built up, I just pour some acetone (same substance as in many nail polish removers) into a small bowl, dump my bushings in there, and then come back later.

Critically important warning: the acetone does not make the CA glue go away, it just temporarily dissolves it. If you fish your bushings out and just dump the acetone down your drain, the second it comes into contact with water that CA glue will turn right back into CA glue — in a stringy, big, sticky, drain-clogging mess.

I tend to fish my bushings out with a skewer, set them aside, add some water to the bowl to solidify the CA, fish it out and dump it, and then add more water to see if there’s any CA left. When I can add water to the bowl without any strings appearing, it’s safe.

I haven’t personally tried nail polish remover (I don’t use nail polish), but I suspect it will work as long as it’s acetone.

Also please read the warnings on the bottle of acetone: it’s not going to kill you, but it’s highly flammable, you don’t want it in your eyes or if you have a cut on your hands, etc.

Mercury also makes a “CA dissolver” product that I have not tried, and other manufacturers may as well.

Here’s the bottle of acetone that I bought, though there’s nothing particularly special about it: Eternal Professional Nail Polish Remover – 100% Pure Acetone

CA Glue: BSI Odorless vs Mercury Flex

Previously my recommendation was BSI odorless, because it was working sufficiently well for me, and I appreciated the “odorless” aspect, even though the same personal protective equipment is still recommended, because it reduced the chance of problems.

Recently however I got a chance to try Mercury flex, and I am now a committed Mercury fan.

Caveat: this is not a perfect comparison: technically I should compare the BSI odorless to mercury odorless, and BSI flex to mercury flex. But I don’t have the time or money to do that right now, so I’ll report on what I’ve seen so far and write more if I get a chance to do more comparisons in the future.

Bob Smith Industries (SBI) Super-gold

This CA glue works great for sure. I got good results with it, appreciated the low-odor aspects, and it comes highly recommended by experienced pen-makers like Toni Street.

But even with my technique improving in other ways, I was still having a lot of issues with bumpy CA application that I wasn’t able to get past. I suspect this is in part because I am working somewhat slapdash out of my art studio, rather than in a proper shop: stuff is clamped to the edge of my craft table and for a long time I was using just a hand drill with a mandrel attached to it.

I also found I just wasn’t comfortable without using a respirator: after doing more than one pen in a row I could feel some tightness in my chest, as it’s hard to perfectly ventilate a craft room, and I didn’t want to risk long-term health issues. So I wasn’t getting as much of a benefit off odorless as I hoped.

One nice thing about Super-Gold is that it does dry pretty fast, which BSI notes is one of the features — but I believe it was also part of my problem, along with the technique I’d come up with for applying it in my make-shift setup: I was spraying the barrel with accelerator, which was helpful, but also meant some of it hardened instantly on application, making bumps more likely.

I changed my technique to use accelerator afterwards and it was smoother, but I was still getting more bumps then I liked, and my sanding time was long as a result (and sometimes I’d have to go back and re-apply CA because I’d had to sand so far to get rid of a bump that I went right down to the clay and had to start over again.)

Mercury Flex

When discussing my lumps and bumps, a friend encouraged I try Mercury flex — it’s not odorless, but it’s thin, and also had a great track record when working on polymer clay pens.

I’ve found that the slower cure time is making it much easier to smooth everything and reduced my CA sanding time by almost half per pen. It’s a bit more likely, with the thin CA, for it to get thrown off the pen and land on clothes/items around me, but using less each time and reducing the rate of rotation has helped a lot there.

The downside is I am also having a few more issues with the odor: when I do more than one pen in a session, I’ve started to notice a bit of dry eye that may indicate some issues with the odors affecting my eyes also. I bought some goggles with a seal online and it’s reduced the problems there though the combination of the two masks is awkward and affects the seal. (Unfortunately a full-face mask with a respirator, which is the best, is quite expensive.)

I’ve continued to use the accelerator afterwards, and am getting much smoother results with that technique and the Mercury CA.

The one problem I still have is I’m now getting grooves around the pen body, I suspect due to the fact that I’m applying the CA with strips of deli paper, and it’s curving up in as I remove the paper, since they occur in the same spots repeatedly. I am considering switching to cling wrap as a replacement, and will write more if it’s more effective.
