How to Crochet a Box - great way to use up yarn and get storage boxes: stiffen with wallpaper paste or liquid starch. Note:(cover the cardboard box with saran wrap and it can be used to help form the crochet box once it's soaked in the stiffener).
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.
