No I've never used on Lycre, presumably you use the light weight snaps. I nearly boobed on the first jacket I added snaps to. I was that busy looking at videos on how you did it that when I came to buying the snaps I got the wrong ones, they were heavy duty ones, more suitable for bags. The fabric I had was not really suitable where there was no interfacing. I finished up having to do some restoration on the back of one snap (out of sight). The good thing was they were only on as a feature and unlikely to be used. Won't make that mistake again.
