I love using stamps and inks on the SHRINKETS shrink plastic . I just added many new stamps and 2 very versatile ink pads Hero Arts permeant ombre' ink pads in shades of pink yellow and orange and in shades of green blue and purple .
This is how a recommend using stamps and ink on the Shrinkets shrink plastic.
When using on shrink plastic stamp on paper first to remove excces ink and then stamp on the shrink plastic . If you still have a heavy layer of ink on the surface of the plastic lay a peice of clean paper ( copy paper ) on the surface of the stamped area and blot up the excess by gently rubbing the paper with your finger. DO NOT MOVE THE PAPER when you rub. This should assure the ink will dry on a non porous surface.
