This project combines two of my favorite things: origami and fused recycled bags.  Fusing is really easy, as demonstrated in this Etsy “How To”.  Once you create your plastic sheet, you can use it like fabric, or as I found, like origami paper. I used an xacto knife to cut the sheet into a rectangle. It is relatively simple to fold, although creasing the plastic takes some effort.  Eight layers of plastic (about 4 grocery bags) provided enough material for one simple origami box. I then used my sewing machine to stitch the edge.  In my first experiment, I tried to fuse the box edges, but the melting process just deformed the box shape.
