I Used that pattern to make a head and coverd it in Antron Fleece t worked real well, I found when using antron fleece you can use the same size pattern just trace the same pattern you use in the foam and hand stich. You can use the same size due to the strecth in the fabric Antron is very forgiving, Remeber if you use a another fabric say polar fleece you will need a seam allowance and will have to enlarge the pattern (wich you can do on a Copying machine)
Hope thaty helps!!
