Steph -
I just learned this technique for a swap! It was so much fun, but it took me a bit to get the hang of it.
This is what I did:
1. Stamped image using black ink on the white glossy card stock. In fact, I stamped the image that I was using for my card all over the card stock (I was going to cut it out later), so I tried to get as many of them as I could on one sheet of paper.
2. Using the white crayon, I colored in where I wanted white to show through on my image ... in the beginning I was very careful about the coloring ... but I found that for my project ... that I liked the random look much better. I just sort of scribbled a bit here and there on my image.
3. I then used my brayer and the ink of my choice ... and brayered the whole sheet of card stock.
4. Using a paper towel, I then rubbed off the crayon. Since the crayon is being rubbed off, I don't think it matters what color your crayon is. This is what got me confused in the beginning.
The effect is very pleasing to one's eye.
Hope this helps,
Kimberly
