Itchy Scissors

Can someone tell me just what a fabric quilted mattress cover is good for? I ask because having just taken it down from the drying rack, my crafter's brain started ticking.

I'm thinking new padding for the ironing board (a bathroom towel currently being the only thing preventing Bill from having diamond shapes all over his solid coloured shirts). I'm thinking quilt stuffing (not that I have a front or a back).

I could make coasters (not that we don't already have 2,491. Oh, or what about padding for boxes and birthday cards???

Given that Bill and I are both currently in our most continent phase of life, do we really need a mattress cover? I really want to know -- my scissors are hovering...
