I never gave it much thought until I read a tutorial on Etsy for fusing plastic bags. http://www.etsy.com/storque/section/howTos/article/fusing-plastic-bags-with-the-etsy-labs/1098/
I normally just use them to line my small trash cans. I have used them also for adding padding to shipping boxes.
Anyways, while looking through the tutorial, I was amazed that fused plastic could be used for things like wallets and handbags. Wow! A few hours later I had an epiphany...and thought I could make shipping envelopes from fused plastic grocry bags, so this am I got out a huge pile of bags, my iron, some scissors and a sheet of parchment paper and started cutting and ironing. It took me all morning, but I made 3 different sizes. Small ones, medium ones and sorta medium ones. They seem to be pretty darn sturdy, so I think I will try them out for my next shipment and see what happens.
