My name is Debbie and I'm brand spanking new to the forum. However, I have been making bottlecap necklaces for awhile now, and bottlecap centers for bows. I attach the pic with spray adhesive. It seems to dry rather quickly. I use the extra large scrapbooking page pebbles for sealing. They are just an epoxy sticker. No mess involved, they just stick on the pic.
