A friend made her own pad, to her custom size. She used plywood put a layer of thick cotton batting,several layers of aluminum foil then she used the insulbrite, heat resistand batting locally available for most quilters, Australia?, and put a 100% cotton fabric over, white canvas, I believe. I thought of doing this but put an additional one inch gingham fabric on top for a grid type that would maybe help to keep track of the 'square' of your blocks, squares, etc. as you press. She then put 'L' brackets that she could swivel to clamp on to her regular ironing board. I think I would go to a goodwill, buy a used ironing board and dismantle it and put the legs on the custom made ironing board and have it in addition to your present ironing board. Just an idea I remember seeing and thought it may be of interest to you. I live in northern Montana, US
