After I made my big board to cover the regular ironing board, I layered batting (1) then covered it with a cotton canvas drop cloth I got at Lowes for about $6. I did the same by stretching, stapling, then turning it over and spritzing with water to tighten the weave. I've had it on there since October and there has been no stretching. I wipe it down with a wet cloth or roller to get any strings off. I love it and it's not scorching as easily as the cotton or regular ironing board cover.
