I really like my dellaQ bag. It has become the permanent home of my traveling scrap project, a striped tube scarf that I am knitting. However, you could totally crochet one, too! I have a bunch of fingering weight leftovers just hanging out in the bag with the project, ready to be toted along at a moment's notice. I am simply knitting in the round until each color runs out and then adding the next. You could easily crochet in the round to use up scraps in this way, too. When I'm done I hope to have a long, squishy infinity scarf that is one-of-a-kind.
