Great idea for a modular knit blanket. One simple shape makes a great quilt. Sidewalk Quilt by Pippa, an original design. Pattern available on her website and a similar version for sale in her Etsy shop.
Crochet Pattern: Rainbow Nesting Bowls (rewritten) goes with the "Crochet Pattern: Color Sorting Balls" that I pinned earlier. What a great learning (not to mention FUN) activity for kids! I'm going to use these as decorative bowls!
