at Joannes you can purchase the silver ironing board fabric by the yard or you can get the canvas fabric that has 1" grid lines on it. both work well for covering your ironing board. muslin is pretty thin so i don't know how long that holds up. a broad cloth may be a better weight. i never bothered with insulbright, i covered 2 different ironing boards, one mini one big block; i just used 1 layer of warm& natural and the cover fabric. i ran a casing around the cover and ran a draw string through it so i can take them off anytime and throw them into the wash. my big one has held up well for about 6 years now...the mini is way older. since i applique and use lots of different 'stuff' (like fusable, and starch) i wanted to be able to wash it when ever.
