I got an awesome tote for my WIPS from my partner for the Use what you have swap this June. I just LOVE it. It's purple what's not to love about that! It's big so I have plenty of room for yarn, patterns etc.
The inside is even lined with a pocket that is a perfect to fit for the Altoid mint tins I use to hold stitch markers and the like (Yes, I do eat the mints before I add pins to them. Sometimes, I even wash them first;)
