This is my first written pattern, so bear with the typos, errors, and weird instructions! I first posted my finished project on r/crochet, and enough people asked for the pattern that I decided to try my hand at writing up the pattern for anyone to use.

The original pattern for this cozy blanket comes from an old magazine that my former college roommate owned. I’ve completely forgotten the name of the magazine (plus I think it was in Spanish?), so I decided to rewrite the instructions in English for anyone who wants to make something with this variation of tumbling blocks.

The basic motif of this blanket is the Y-shaped tumbling block. Like any good tessellation, these tumbling blocks fit together without any gaps, and bonus! when they’re oriented correctly, they join to create an awesome 3D illusion of cubes stacked on each other.

I used 15 skeins of Lion’s Brand Heartland yarn (3700 yards) in 9 different colors. Choose as many or as few colors as you’d like, but for the full 3D effect you will need at least 3 colors.

The size of my finished blanket is approximately 56” x 88”. The size depends on the yarn and hook used and can be customized depending on your needs. Mine fits well on a full-sized bed.

Gauge doesn’t matter for this project. As long as your gauge is consistent throughout, you won’t have any issues joining your pieces. My advice is to make one or two test pieces and use those to figure out how large your project will be!
