bag made out of plastic bags My nephew works at Hagen's who hands out pink bags every year to show support of fighting breast cancer. He collected them and a customer made me a beautiful pink bag like this one from them.
crocheted plarn bag by Thoughtful Rose, she used loops of plarn, and a size H crochet hook. Tight, dense stitches are the key to a plarn bag that won't stretch out of shape (that, and crocheting through both loops). Plarn is yarn made from plastic bags
