Granny square boxes :: I really like the idea. Could be any size of box - just add enough rows on the granny square to make it fit. Might require a bit experimentation on how to apply the squares on the box though.but so pretty.
Chunky crochet basket-I love making these. Make whatever shape and size you want, find something to fit inside snugly and cover that thing with plastic wrap and then spray the crocheted basket with liquid starch and let dry.
