When stamping on fabric, be sure to set with a hot iron to ensure the ink stays permanent. These are also great to use on shrink plastic, so you can make your own shrinky dinks with your kids or for yourself.
Tsukineko is known for its excellent quality inks and pigments. As a printmaker and stamp maker, Tsukineko inks are the ones I prefer to use due to their color quality and consistency. And I've tried a lot of brands!!
