so, i've seen the links and postings about sewing fleece mattresses/liners. right now, i have 2 towels, a uhaul pad and then the fleece on top for my bedding. the fleece comes up and over the coroplast and is held in place with binder clips. it sounds like the pre-sewn mattress pads are way easier to change out, but i don't have a sewing machine at my disposal. any other ideas for how to make a cage liner? i doesn't look like it really can be hand stitched (my cage is 2x4)
