My mom did several granny squares in that exact color and pattern! I'm not sure if she ordered a kit or just had the yarn for it (there's always yarn!), but seeing this really helped me out on a night that I've been missing her strongly. Thank you for the unintentional gift.
ETA: I believe somewhere, possibly hanging on the wall in my brother's house, is the blanket she made from them. I'll have to check when I get back there.
