#1.) you take a piece of paper: this one here is 9" x 12" Strathmore Watercolor cold press 300 gram/meter square
#2.) you create a painting, design, image, cut 'n paste, etc. on a piece of strathmore paper
#3.) This one I used a tip of a wooden orange chopstick and a cap of a watercolor tube and dipped into saturated water colors without clean-up in between paint dip. For full paint vibrancy, clean tip before re-dips.
#4.) You fold the paper lengthwise (so you can make a set of matching cards)
#5.) You carefully center it and cut the card in half. (easier done on a cutting board)
Now you have a beautiful set of cards ready to use :)
