I just received the Natural Brow in light brown #12 from Headcovers and I really think they could look great. I am looking for any advice on how to apply them so that the backing doesn't show. When I put them on just temporarily, they kinda looked like stickers because I could see the gel backing. I am also not sure how to trim them without ruining them. They really don't need trimmed if I could just hide the backing better. Any help out there? Thanks so much for any advice.
