With only a few cuts in your pencil’s rubber you can make a small stamp – great for decorating envelopes, cards and gift tags!
I’ve used water colors, two pencils and a scalpel. First use the scalpel and cut the shape you want from the rubber. Too detailed shapes are difficult to make, but a heart and a clover or a star is definitive possible. By using not too much water on the colors you’ll get the perfect stamp mix. Good Luck!
