A nifty new way to keep your sandwiches! Introducing the Sandwich Keeper! I made mine out of scraps of fabric and I think vinyl, or something of the like that was once advertised to be used as rain repelling fabric.
I took the two pieces and sewed them together along with a Velcro fastener. I cut the edges with pinking shears and viola! a reusable way to transport your sandwiches. To clean you just wipe off the plastic side with a little soap and water.
