I've told you ten compelling reasons to ditch the plastic carrier bags. But what are you going to do with all the bags you have collected already, stuffing up that cupboard in your kitchen. You know the one! Well Cindy at My Recycled Bags.com has dozens of patterns for crocheted bags made of cut-up old plastic bags. I've made something similar myself, but Cindy is a far more talented designer than I am, and her bags are much cooler.
She also has patterns for other items such as Barbie clothes and pan scrubbers, and patterns using other recycled "yarn", including the tape from old VCR and audio cassettes. As well as practical grocery bags she also has patterns for elegant little evening bags (honestly!), coin purses, funky shoulder bags and other items such as peg bags and water bottle holders. And if you don't feel able to make the items yourself (she gives full instructions for them all), you can buy the items from her at very reasonable prices.
