C2C Crochet Heart Blanket Square: Free Crochet Pattern

Have you ever seen vintage quilts that had heart squares, and wished you could make one with crochet? Maybe you just love hearts!

It’s the February blanket square for the 2020 C2C Crochet Mystery Quilt, and I think you’re going to love it!


When I designed this C2C heart crochet pattern, my biggest inspiration was designing around the idea of the 2020 C2C Crochet Mystery quilt. Each month there is a special block for that month, and this one is for February as a part of that blanket. As I browsed through different quilt squares, I always came back to having my eye drawn to the patchwork heart quilt squares. Maybe it’s because the main holiday for February is Valentine’s Day! Wouldn’t this square be just beautiful with an entire blanket made from heart squares? It would be so pretty!


Isn’t it cool how we can replicate patchwork quilt squares with crochet? For this crochet blanket square, you’ll be using basic C2C crochet techniques to create the square. You’ll need to know how to do the basic C2C crochet stitch, made from double crochets, chains, and slip stitches. It also includes color changes. You can do these by either carrying the colors, or by creating yarn bobbins that you join to the square as you need a different yarn color.

If you are making this quilt block as the pre-filled patchwork version, you’ll use the chart below. If you are using worsted weight yarn, your square will have slightly larger dimensions than if you’re doing it with DK yarn. Both work, but you’ll just want to keep in mind that they will end up different sizes due to using a thicker yarn.

The block pictured in the pictures above is the temperature blanket version, and below is the patchwork version.

Follow the chart working diagonally, starting from the bottom right corner, and working your way to the top left corner. To get the written version of this pattern, along with the watermarks removed, it is available with all 11 other blocks in the 2020 C2C Mystery Quilt on Etsy or Ravelry!
