Knit Yourself a Puzzle Cube

I say this a lot, but I love it when people knit things that surprise me, make me think or make me laugh. This one kind of does all three! It’s not a new pattern but I think it’s worth taking a look at, and it would be a super fun stash buster to keep on your desk as a fidget.

It’s also a great conversation starter because this is the knit version of the Soma Cube (which also happens to be the name of the pattern), which was invented by Piet Hein in 1936 while he was listening to a lecture about quantum mechanics.

There are seven different pieces of various shapes that can be fitted together to make a cube. But the really cool thing is that there’s not just one way to put it together, there are in fact 240 different solutions! So you or your kids or anyone who happens by can play with it over and over and come up with different ways to make the cube.

It looks like this project is made with worsted weight yarn, though the pattern page on Ravelry actually doesn’t say. It looks like people have used fingering weight, DK and worsted weight yarns, which would make cubes of different sizes but the pieces should fit together all the same. There are even a couple of crochet versions!

I was looking at different projects and one person commented that it’s worthwhile to knit the pieces in the order they are given in the pattern because some of the later pieces are “strange and bewildering.” Which sounds like something I absolutely want to sign up for!

Despite the weird shapes there’s not a whole lot of finishing on each piece. The designers used polystyrene beads to fill their blocks, but you could also cut pieces of foam to fit.

The pattern is available on Ravelry.

Knit Toys Made Out of Squares

Halloween Toys to Knit

It’s kind of coincidental that I recently posted about patchwork blanket knitting patterns right before reviewing a book that makes a patchwork blanket, but this one would also be a great choice if you’re looking to bust some stash and learn a lot about colorwork knitting at the same time.

Knit an Heirloom Blanket by Annah O’Leary includes charted designs for 50 colorwork blocks worked flat that can be combined to make a blanket or used in other projects. The book calls for worsted weight yarn but also offers suggestions for using fingering, DK or even bulky yarn, which will give you blocks of different sizes.

It opens with a section on materials and tips for choosing colors and maintaining contrast among blocks across a large project. There’s also information on how to read charts and colorwork basics such as maintaining tension, measuring gauge, catching floats, holding yarn and yarn dominance, among other things.

There are 196 squares (14 by 14) in the blanket shown on the cover, which, including the edging, makes for a blanket that’s about 79 inches, or 200 cm square knit in worsted weight yarn. You can adjust the size as needed by working more or fewer blocks, especially if using a different weight of yarn.

The sample was worked in Cascade 220 and the book includes the amounts of yarn used in each color so you can knit a blanket exactly as shown. Or use stash and leftovers from other projects to make a possibly less harmonious but more meaningful project.

Colorwork patterns are arranged into 10 themes: flowers, tiles, diamonds, stripes, peaks, woven, sky, leaves, lovestruck and architecture. They’re also rated by skill level on a range of 1 to 3 balls of yarn. If you’re newer to knitting or colorwork in particular, you can start with the easier squares and move up as you build more skills.

Each pattern is shown as a large black and white chart with three or four possible color variations, though or course you can also go your own way on the colors. There’s also a knit sample of each block pictured at the beginning of each pattern section.

There’s also a section to help you finish your blanket, including tips for weaving in ends, blocking, joining squares and adding a border. She also suggests different project sizes and color palettes for smaller scale projects.

In addition to the big blanket there are five other project ideas including a baby blanket made of 6 by 8 squares, a hot water bottle cover, a couple of pillows and a wall hanging. These are sure to give you ideas of different ways to use the blocks in other projects.

Knit an Heirloom Blanket includes lots of fun colorwork blocks and ideas for using them that are sure to appeal to those new to colorwork as well as those with more experience. Even if you never knit a full blanket with them, you can add these motifs to your collection to work in other projects.

About the book: 144 pages, paperback, 50 charts and 6 patterns. Published 2026 by David & Charles. Suggested retail price $25.99.
