About the Patchwork Prism Baby Blanket
The Patchwork Prism Baby Blanket was inspired by Mary Maxim’s “Prism” yarn – it’s wonderfully colorful and so much fun to work with. I had used the “Prism” yarn for the Mary Maxim kit of the Birthday Sorbet Baby Blanket. The idea of using that particular yarn with a solid color and lots of texture really called out to me. So, after some fiddling with the stitches, the placement and some ideas, the Patchwork Prism Baby Blanket was born!
My testers rated this pattern as “Intermediate”, so it does require some concentration for the first square or two. But, don’t let that scare you. The squares use basic stitches with the occasional front post stitch placed in there and some back posts for texture. Also, there’s only 4 ends to weave in with each square! Instead of cutting the yarn with each round, I recommend simply carrying it up with your work. There are also videos to help you along with the square, the join and the border.
On a side note, I want to extend a big “Thank You!” to all of my testers that helped with this design and a huge “Thank You” to Mary Maxim for supporting my idea!
About the yarn
The yarn used was provided to me from Mary Maxim. The solid color (white) is Mary Maxim “Mellowspun DK”. This is a DK / #3 light weight yarn that is 100% acrylic. It works up beautifully, is machine washable and there are LOTS of colors to choose from.
The colorful yarn is the wonderful, self striping yarn named Mary Maxim “Prism”. It’s also a DK / #3 light weight yarn that is 100% acrylic. It works beautifully with the Mellowspun DK and comes in gorgeous colors to choose from. For this particular blanket, I used the color “Rainbow”.

Joining the squares using the “Zigzag Slip Stitch Join” method
-
Before beginning the join, lay all squares out to determine placement of squares and take a picture to reference.
-
Lay out bottom row and next row (See picture below for visual reference).
1. Using removable stitch markers, mark the stitch that is after the first ch-2 sp and the stitch that is before the next ch-2 sp on each of the two squares sides that will be joined together (the ch-2 sp is easy to find, but the next st can be more difficult)
2. Using CC, make slip knot
3. Insert hook in bottom (closest to you) chain space in the right side square from front to back, then insert hook into the slip knot. Pull the hook through the ch-2 sp with slip knot
4. Insert hook in bottom (closest to you) chain space in the left side square from front to back
5. Work slip stitch
6. Insert hook in next st of right side square, work slip stitch
7. Insert hook in next st of left side square, work slip stitch
Continue repeating steps 6 – 7 until you come to the end of the row ending with the final slip stitches in the chain-2 spaces.
Joining the columns
Work the join for the columns the same as the rows, but when you come up to where the columns and rows intersect, work over the row join when slip stitching into the next block’s chain-2 space.
Border
Notes:
-
The border works with any stitch increment, so being off by a stitch or two isn’t critical
-
RS is always facing; do not turn your work
