Plastic grocery bags can be recycled into crocheted art projects that are very sturdy. I have used hundreds of plastic grocery bags to crochet freehand, without a pattern, a large carrying bag and a large day pack. The bag has been used for a few years now and is as sturdy as ever. I just finished the day pack, which will be good for carrying bulky but lightweight items, like coats or sweaters. This is a great way to reuse plastic bags.
