Recycling plastic grocery bags and plastic shopping bags is nothing really new, but I like to do my recycling without smelling up my environment. If you merely return your bags to your local grocer for recycling, they will melt them down to make new bags. This emits more pollution into the air. I have also discovered that fusing plastic bags with an iron releases noxious fumes into your home and I don't think that's any better. So, in come the scissors.
Step 1: Lay out a plastic bag.
The best bags for this are the really thin ones you get from the chain grocers and places like Walmart. The thicker ones are more difficult to work with.
Lay out a plastic bag, tucking in the side seams and smoothing the bag flat. It doesn't have to be perfect.
