I recently purchased a pack of Brusho Wax Resist Sticks and had a play with them to create these backgrounds, ready to be stamped on. An on-line video by Eileen Godwin inspired to me to give it a try.
I used one of the crayon like sticks to draw lines on a blank tag. I then used various shades of Distress Oxide Inks. The crayon lines do not take up the ink, leaving the original drawn design.
