A whole hobby has arisen around the art of rubber stamp carving, and not just by letterboxers. Enthusiasts carve stamps using erasers as well as commercial soft block carving materials, using Speedball knives, pen knives or Dremel wood carving tools. Part of the tradition of North American letterboxing is to create your own stamps; most letterboxers value finding a hand carved stamp much higher than a store-bought one. Stamp carving isn't all that difficult -- you just need to give it a try.
