I've found that you can't use just the Insulbrite alone, you need at least one layer of warm & natural or other cotton batting, as this absorbs some of the moisture from the heat, so it works better. I made an extra long table runner, using the zig-zag pattern I found online for my son and DIL for them to use on their buffet because the top was starting to get some heat damage from their coffee pot. My DIL loves it and says it works like a charm and she just tosses it in the washer and dryer - works great.
