Try this at home!
Cut out a rectangle from a styrofoam meat tray, to fit your cardstock.
Draw a simple design with a sharp pencil.
Use acrylic paint (tube) and put a very very small amount of color on the stamp.
Turn the stamp over, on to the cardstock front, and using a brayer (or rolling pin, or dowel) press evenly over all the foam. Lift stamp, and you have a card! Embellish with pen, or any other media you like! You don't have to be an artist to have your card come out really fun! Try it!!!
