To make your own block prints, you will need: foam meat trays, water-soluble block printing ink, brayer, cardstock, and a large spoon.
We used the opposite end of a paint brush to press our designs into the foam. You could also use a dull pencil.
It should look like this. Flip it over to make your print, and use the back of a large spoon to press down firmly on the paper. Lift the foam up carefully to reveal your design.
