I have 3/4" and splurged for the "top choice blondewood plywood. I have found fabric listed as ironing board cover and says it is "woven of 100% cotton with a unique aluminized coating". It is listed as silver but looks more like a heather gray instead of the shiny metallic looking stuff I was finding earlier. I think I will go with that and I might or might not put a cute cotton print over it if I decide I need some whimsy in there. There is LOTS of white furniture, lol. If I do add another fabric I will staple it separately so it can be removed and/or changed without disassembling all the layers. Thanks to those who have answered so far, and I'll keep you posted! It might be several days as we are still building the furniture and I have to get to the store to get the fabric.
