Stamp InkMy favorite for crafting is Staz-on, however, it is permanent.
Pencil
Instructions
Start by sketching a rouch outline of the stamp shape you want to make directly on the eraser with a pencil. You can get as detailed as you would like with your sketch.
Then start using wood carving tools to remove the eraser material. I like to start by removing as much material as possible from around the outside.
Once your outside is fairly clean, you can start adding details to your stamp. Again, use whatever size and shape of wood carving tool works best for you.
Once you think you are done, test the stamp with some ink on some scrap paper. You may find you need to remove more material in some areas to get a clean impression. Keep working with the stamp and the wood carving tools until you have a stamp you love!
