If you are into upcycling then you will want to know how to fuse plastic bags together. Etsy has this great tutorial. I was very excited when I found it and learned how to make plastic bags into a more durable "fabric."
I love this technique because the sky is the limit. Here are a few of the items that I have made from fused plastic.
And you may have already seen it but it is worth repeating. Here is the purse that my sister made for me from fused plastic garbage bags. (Don't worry they never had smelly garbage in them but they were upcycled from donation bags from the local thrift store.)
