I get the ripple quite frequently after applying the French Lace. I try not to use SFS as if falls apart on me after the second attachment so I have been ordering just the French. (The old SFS was sturdier)

Are there any tips in combatting this phenomenon? I use 3-mil CC contour up front.

I thought it was caused by stretching when attaching but even if I just lay it flat and gently attach I still get it.

I thought it was because the lace is flat no shape or curve, but when I dry the unit on a styrofoam head it riples there as well. i don't think there is all that much curve

Any advice would be greatly appreciated!
