After about an hour of playing around with the shapes, I settled on this arrangement. I had an old earring attached to the long rectangle on the left side but it broke during the final stitching. Seems like that was what happened to it's mate originally. There are a couple of paper fasteners along the bottom. They were the only other warm metals I could find for embellishment except for buttons which didn't seem to work. Still looking for the right thing but essentially finished.
Next time I try this I will try the soda can pieces instead of the coffee bag.
