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

Brush Cane Video Tutorial

My very first video tutorial! If you’d like to see more, please subscribe to my YouTube channel:–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:

Spliced Paradox Cane Tutorial

I am now making video tutorials also: my channel is at–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.


  • 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.

Burgundy Flowers Tutorial

This tutorial is for people comfortable making skinner blends and skinner blend plugs. If you haven’t done either before, here’s some videos on making Skinner blends, and some on how to make a skinner blend plug.

It’s a simple tutorial, and I would encourage you to not try to make yours exactly the same as mine — if you want to make different cuts or colors or flip some pieces differently, you should. Learning how the choices you make affect your final cane is a key part of the process.

The Cane

Here’s how the final cane looks used on pens at different sizes and parts of the process.

Lessons Learned

I was fairly sloppy in this cane. As you can see in steps 1 & 2, the edges aren’t lined up and I didn’t take a lot of care forming the plugs. It works out okay because I never try to combine everything into one big hexagon and slice pieces from it, so I don’t have to worry about one end of the cane being different from the other, but it could cause an issue if that’s how you do your canes.

In retrospect, I ended up with too many large blocks of white (those two pure white corners) in the final design. If I were doing this again, I would either do more cuts to the original square or, more likely, simply change how I make my triangle from it. Specifically:

If I’d turned the the mixed-color sides (marked with red circles) into points instead, and turned those points (marked with blue circles) into sides, I think the final cane would look better.

Even at the end, I could have avoided my “big blocks of white” problem if I had chosen to flatten the whitest tip (the top of the triangles in step 9) instead of the darkest tip (the bottom of the triangles in step 9) like I did.


Step 1: Create two skinner blend plugs from Dark Mineral Grey and Pompeian Red or your choice of colors.

If you are trying to make a cane identical to mine, I made about 10g of the red, and about 7.5g of the grey, and the recipes are linked here.

I did a straight skinner blend with the same amount of white as each color, but offset on both sides so you have pure white on one end and pure color on the other.

Step 2: Put them together in a block, with the light next to their dark and vice versa.

Why? The point of all of these flips and slices is to mix up both color and tone (how dark or light the color is due to black or white being mixed in) to create contrast in the final cane. Without that contrast, the final cane will be muddy, particularly when reduced small enough to be used in a pen.

Step 3: Slice diagonally and flip one piece, bringing grey to red and vice versa.

Step 4: Repeat slicing across the other diagonal, and again flip one side before rejoining.

Step 5: Slice off all four corners

Step 6: Swap corners around. I moved every corner one step clockwise and flipped only one of them: the one that starts in the bottom left of Step 4 and is in the top left corner on step 5.

I flipped it to bring opposite colors together.

Step 7: Slice across asymmetrically and flip one piece before bringing them back together.

Step 8: Begin to turn it into a triangle.

I did this by gently squeezing the bottom left into a corner and flattening the top right.

Step 9: Reduce your cane to about two inches long, and then slice it down the middle.

Figure out how you want to combine it to make your final cane that you’ll re-shape into a triangle.

Step 10: Reshape your combined cane into an equilateral triangle and reduce as needed.

I’d like to extend thanks to both Meg Newberg (via her Cane Builder subscription) and Fiona Abel-Smith, who both have done canes in the below style and were the first introductions I had to this style of creating a kaleidoscope from a skinner blend plug.
