''In my opinion the more you stretch the lace front the worse the accordian or ripple effect becomes....'' ''I wish I knew what causes this but I simply dont buy the fact its acceptable and you can imagine how much more frustrating it is when this happens on a custom piece !!!!!''

Hope you don't mind me quoting you but you answered your own question in your post! It's exactly as I answered in my post too. For those that wear lace, don't continually stretch it to fit-lace in it's nature has elasticity, but like a good pair of used underwear, it'll eventually get baggy! Regards
