Swimsuit recycling?

Hi folk-- Just replaced my fading into oblivion speedo with a new model and got to thinking about the retired suits that I keep around--sometimes to double up... for modesty and drag/resistance. But some after a while even become useless in that capacity. While there doesn't seem much you can do with the totally worn to a frazzle suits, I do kind of wonder if there's any way to salvage/re-use them for something--not even necessarily swimming... although a quilt full of faded squares probably doesn't cut it. Still, maybe some of you have made some sort of creative use of unwearable suits? Just one of those things a person thinks about instead of having a life... ;)
