This new technique creates straight lines, checkerboards, and new designs. You will need: a plastic card, a surface to paint on (here I am using a piece of cardboard with a plastic layer over the top), a "palet" to paint on (here I am using a shorter piece of cardboard with a plastic layer over the top), ArtWaters medium, and an ArtWaters color. Start by pouring ArtWaters medium into the center. Next, do a straight line of ArtWaters color onto your palet.
Dip your plastic card onto your palet color, covering the bottom of your card.
Now place your color covered card onto your ArtWaters medium.
