Get a band-aid about the size of the boil you want. Then, dip some tissue (toilet paper works best) into a mixture of PVA glue and water, and form it onto the band-aid. Make a groove by pushing a pencil about halfway into the tissue. Wait for it to dry and cut around the hardened glue and tissue. Peel the backing of the band-aid off and place it in the desired location. Use makeup to blend it onto your skin.
