when you cut your side mats leave a extra chuck of mat where you holds are at. after you stretch and glue down the turf just cut away the extra. same with the bottom mat, mold it down in the foothold and cut along the crease after you glue it down. get you a can of contact cement and do a couple coats on the mat and ski and let it tack up for about 10 min. when you lay the turf down it will instantly bond and stay in place making it easy to mold into the holds. a heatgun helps you make the curves easy.
