The synergy square is an interlocking crochet blanket square. With the suggested yarn, it measures approximately 9”, but changing yarn or hook size can give you some variation in sizing. This pattern will be free on my blog at https://kickincrochet.com/synergy-interlocking-crochet-square beginning March 10th. You can also purchase a PDF copy of this pattern in my pattern store. The pattern includes written instructions, charts, photos for important steps in the first few rows, and a complete video tutorial.

For my sample, I used WeCrochet’s Wool of the Andes Worsted in Gull and Calypso Heather with a size H crochet hook. I have also made a sample using Lovecraft’s Simply Aran and an H hook. This yarn gave me a square that was about 10” instead of 9”.
