I made these squares shortly after learning how to crochet, and then they sat on my shelf for 18+ months. I sewed them together with the terrible Red Heart yarn that I had left over from the project. I’m donating the rest to charity. I did a simple double crochet around the edge with three stitches in the corner stitch. I will use this to draw cats to a spot and keep them away from other furniture… as with many of my blankets.
