When I found out my cousin was having a baby, I started to brainstorm ideas for a new blanket pattern and decided to go with something quilt-y. I was messing around with online quilt generators (like this one) and fell in love with the diagonal stripe quilt block, so I whipped up a crochet version using the corner-to-corner (c2c) method.

The blanket is coming soon(ish), but the corner-to-corner crochet blocks are super versatile and can be used to make several different designs. A few months ago, I shared my favorite layout ideas on Instagram. For the Quilt Block Pillow, I chose to go with a diamond layout on each side, but feel free to mix it up however you wish.

c2c Pillow Tools

You’ll need four different colors of worsted weight yarn to crochet your corner-to-corner pillow, so I used one of my favorite acrylics — Brava from WeCrochet — in Dove Heather (light grey), Silver (dark grey), Tidepool (teal), and Tranquil (minty green).

Brava is soft, durable, and washable, so it’s an excellent choice for a couch pillow. My dog is likes to chew on her toys on the couch, so my pillows go through the wash A LOT.

Because I love to match my hook to my WIP, I chose a K 6.5 mm Streamline Swirl in Pisces. It’s a galaxy swirled resin hook from Furls Fiberarts and the color is so, so, SO yummy. If you’ve been following along, you know that I love all blue everything, so this hook is no exception. The Pisces is primarily navy, with swirls of clear and sparkly silver. I should take a video of it sparkling in the sun because damn… it’s gorgeous.

Anywho, the hook features an ergonomic design which works out great for my knife grip. Corner-to-corner projects work up really quickly for me once I get into the rhythm, and the Streamline Swirl slides right through with no snags on my Brava yarn.

Corner-to-Corner Pillow Pattern Notes

  • I use a ch-2 for double crochets, so I chained 5 for increasing rows of c2c. If you typically use a ch-3, you’ll chain 6 and dc into the fourth ch from the hook.
  • If you’d like to make a removable pillowcase, you can use buttons on one side of the corner-to-corner pillow.
  • For best results, it’s recommended that you wet block your squares before joining.

Diagonal Stripe Square Graph

Use the grid below to corner-to-corner crochet 8 diagonal stripe squares. Each graph square represents one c2c block. You’ll increase in rows 1-9 and decrease in rows 10-17.

Assembling the Corner-to-Corner Pillow

  • a.) Lay two squares on top of each other with the “wrong” sides together. Join yarn to the corner (I used Tranquil) and sc across the top. You’ll put three sc into the top of each c2c block.
  • b.) Continue until you’ve reached the edge of the squares.
  • c.) Lay the next two pillow squares on top of each other with the “wrong” sides together. sc into the corner, making sure to keep tight tension to minimize gapping at the center join. Continue across. Trim yarn and weave in ends.
  • d.) Rotate your project and repeat the above steps to complete the perpendicular join.

  • e.) When you reach the center, simply sc over the sc’s from the previous join.
  • f.) Repeat this process for the back panel of your pillow. Trim yarn and weave in ends.
  • g.) Place the front and back panels on top of each other, with the “wrong” sides facing in. sc around the pillow placing 3 sc in the top of each c2c block and 3 sc in each corner.
  • h.) When you’ve completed three sizes, slide in your pillow insert. Continue sc-ing around the edge. Invisible join to finish. Trim yarn and weave in ends.
