I made a blanket! A bit of a long-time no-post, but this is what I was working on from February to May this year. I did (sort of) use a pattern, I will link it here if I ever find the link, but it was a pretty standard granny square pattern that you could find in a lot of places. Then I improvised the border because I lost the pattern.
I used cotton yarn (which some might frown upon), but I prefer cotton yarn. It’s about twin size, eleven rows of eight squares, and they’re about six inches each.
