Use to ensure even paint distribution. Size 4"x4" A StampBuddy is just a little pad like foam on plastic where you pour paint onto. It is very easy to rinse out afterwards - ready for a new color! It ensures that your stamp has an even distribution layer of paint on before you stamp. You can also pour more than one color of paint onto the StampBuddy to get neat looks for your stamping. Personaly I like to use Jaquard or Handy Art Fabric paint (for fabric paining and block printing on fabric) but any acrylic paint can be used on the StampBuddy!
