With its super fun no-sew construction and its boundless color-play potential, our Prism Blanket is a totally absorbing knit!

Prism Blanket | Purl Soho

The building block of this blanket is a bias-knit square made with simple increases, then decreases, plus lots of relaxing knit stitches in between.

A color change halfway through each square creates kaleidoscopic triangles that tumble across the surface of the blanket… An artistic process (which color next?) that results in a work of real craftsmanship. 

Prism Blanket | Purl Soho

The clever bit is how you attach each new square to its neighbor by picking up stitches as you knit. This means no interruptions and no pile of squares to deal with at the end! Don’t worry, picking up is easy to do, and we have a step-by-step tutorial that makes it even easier.

The satisfaction of this pattern is enriched by our absolutely gorgeous Good Wool. One hundred percent Andean highland wool, this natural beauty is durable, warm, and softer than you may expect! This yarn is one of our favorites to knit, and creates a garter fabric with a lofty bounce!

Good Wool’s heathered spectrum always sparks our imagination, and with almost forty colors, there’s lots of room to play!

We’ve put together ten lovely Prism Blanket Bundles that come in both crib and throw sizes, or you can get extra creative, and make your own!

NOTES

CONSTRUCTION

You will work this blanket in one piece, beginning with the bottom left square. You will work in columns, one bias-knit square at a time. When necessary, you will pick up stitches from an adjacent square (or two!) in order to continue seamlessly. Don’t worry, it’s easy and we explain everything!

PLANNING CUSTOM COLORS

SPECIAL INSTRUCTIONS

K1 TBL (KNIT 1 THROUGH THE BACK LOOP)

In this pattern, every time you knit through the back loop, it will be into a yarn over from the previous row. To do it, just insert the right needle into the back leg of the yarn over and knit as usual.

For more help with this technique, visit our tutorial at purlsoho.com/create/knit-through-the-back-loop-k-tbl/

SLIP STITCHES

Slip all slipped stitches purlwise unless otherwise specified.

PICKING UP STITCHES

For the cleanest pick-up edge, insert the needle into the outer most bump of the garter ridge edge.

Visit purlsoho.com/create/picking-up-stitches and scroll down to the “Along A Vertical Edge: Garter Stitch, Into the Ridge” section to see exactly how to pick up stitches for this project.
