My daughter has purchased a couple of frozen meals from a company called Freshly. The meals come packed with those ice packs and insulated with cotton batting. I was going to discard the insulation until I removed it from the plastic and thought, hmmm.
The pieces are 36x16x2 and I thought maybe they would make decent absorption panels if I built a frame and wrapped them in fabric. I could, and probably would double the thickness on the panels. Any thoughts on this?
