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.
Crochet in Color: Lots of Free patterns. I always go with the smallest hook for baskets, bins, etc. More useful if you don't have to shape them. The only time I use a bigger hook is if slouchy is what the design calls for. Make Crocheted Baskets!
