I agree, go with Swiss and just get Debbie's knot sealer. The French Lace gave me a LOT of heartburn as it is very difficult to disappear properly. Even if you do get it glued right (takes heavy strength glue), it will eventually start to show through in a few hours, especially if your forehead sweats after walking, etc.

SFS is the way to go. May as well go all Hollywood on yourself if you're going to do this right.
