Personal Stamps to Enjoy
This is perhaps the best stamping book I've seen! The book is crammed with super cute stamp templates (including alphabets), step-by-step stamp carving instructions, and loads of inspiration for finished projects.
Note that the book is written in Japanese, but patterns and schematics are included. Crafters who cannot read Japanese but who have some stamp carving experience are usually able to interpret the instructions without any trouble, and others can use the projects as inspiration for their own creations.
