Nostalgic and cute granny squares: Crochet lessons, part 1, 2, 3, and 4. Part 1 uses one of each color of yarn, so the amount of yarn is less. The finished squares have been unraveled and are included. (Photo 6) Parts 2, 3, and 4 are unused. If you make up to part 3 and join them together, you can make a neck warmer like the one in photo 11.
