What you need for this process is a foam pad, some paint and either a foam brush or small pieces of sponge, and of course the printing block.
The foam pad provides just the right amount of cushioning to produce a clear print. Place your fabric on the foam pad. Put some paint on a palette, paper plate, or foam tray - whatever you prefer to use. I save foam meat trays to use for paint supplies. Draw some paint onto the sponge or brush, wiping off the excess and use it to dab paint onto the wooden block. You should be able to see that the surface of the block is coated with paint but not globbed on anywhere. Position the block where you want to print and press down firmly on the pad. Remove the block, apply more paint, and repeat the process. It's that simple!
