I'm trying to figure out the best way to make the edge of my unit undetectable to the touch. For example, if someone is running their fingers though my hair, I'd like it to be as undetectable as possible. I realize it won't be completely undetectable, but I'd like to get as close to that as possible. I was wondering if using glue around the very edge of the piece, with tape behind the glue, does a good job of making the edges flush against the skin better. Right now I use French Lace. Thanks for any input.
