Go to the tack store and ask for a wool felted saddle mat , they are about 1/4 inch thick , 30" X 30" and run any were from 20 to 30 dollars. I cover my with a sheet of muslin to keep it clean, and I love it. I can't see paying more money for the smaller ones, I do have a small one form the quilt store to take to classes but the bigger size works wonderful on my ironing table.
