To remove a bookplate, you will need paper towels, wax paper, distilled water, water colored paper, a weight, and a blunt knife. Cut the paper towel slightly larger than the bookplate itself with scissors. Wet the paper towel and blot it dry with another piece so it is damp. Fit the paper towel over the bookplate, put the wax paper on top of it, and let it sit under the weight for twenty to thirty minutes. Once the paper towel has soaked into the bookplate, gently peel the bookplate off with a dull knife, removing any excess paste with a damp paper towel. To remove any excess moisture, cover the spot with watercolor and wax paper, and leave it under the weight overnight.
