It's a japanese stamp book and it shows you how to carve your own designs from an eraser. It has many very cute designs in it. It has also many tips and examples on how to use your stamps (like printing on fabric :) ). You don't need to speak japanese to understand the instructions, because the book has step-to-step photos. If you like to get the book, theres a great seller at ebay, pomadour , who sells directly from japan. She is a very nice lady and she has tons of japanese crafting books, shipping free.
And this is what I made so far from the book.
