If you're using a piece of printer paper, fold it in half twice so it's thick enough to stand up by itself. (You can glue it together now, but I prefer doing this once I've painted it -- that way, if I somehow make a mess of it, I at least haven't wasted my time on the gluing too.)
Decide whether you're going to create a design on just the front of the card, or on the front and back. Then using a wax crayon (or candle) draw the design. Keep it simple -- the wax-resist technique works best with strong lines, not fussy details.
To see what you're drawing when using a white wax crayon, put the card or paper near a light source such as a lamp or window, and you'll be able to see the wax shining on the paper. (If you want some simple ideas to get you started, look at these free Christmas stencils.)
Next step is to paint the card and reveal your Christmas design!
