Crafters and artists have been leading the way in recycling by finding really inventive ways to reuse various materials. The totes crocheted from plastic grocery bags are one of my favorites. A few years ago Leisure Arts published a series of books on crafting with recycled materials. We purchased the set for our library collection and they have been really popular. Although I don't think they are still in print, I did find listings for them on Amazon and several resellers. Shopping.com has reviews on them, too.
