I learned to crochet a few weeks ago and ran out of yarn so i made this bag out of plastic bags as a practice project. To make the plastic yarn see: http://www.cutoutandkeep.net/projects/yarn_from_plastic_bags this project took about 8 plastic bags to make. It's super handy to put dog toys, treats, poo bags and water bottles in so they don't make my handbag icky.
