How to :

If you use a potatoe, cut it in two parts.

Click on the design of your choice and print it. Then reproduce it on your potatoe, piece of rubber or piece of foam. If you use a piece of foam, you just cut the fom and empty the white parts and glue it.

If you use a potatoe or rubber, the black pieces must stick out as the white ones are carved. When it is done, glue your stamp on your block and enjoy.
