Lisa and I played for several hours with our inaugural ATCs. (Of course, I also had to check out her studio and while she mostly loves making art at her dining room table, she also has a way cool nook in her well-lit basement.)
Layer 2: I used 4 different watercolor crayons to lay on color, mixing some (orange and red in the lower right) and leaving others alone (yellow in the upper left). There's a green border around the outside of the card.
The beautiful thing about watercolor crayons is - when you add water, they bleed and blend and swirl together in the most amazing way. If you use just a little water, you get great control. More water and they tend to run together in really beautiful ways.
Layer 3: I had some green gems with silver borders. So I put those on the card and began to draw around them with the acrylic paint. The edges were too harsh - the marker tips didn't lend themselves to blending at all. So I colored over those with a lighter green watercolor pencil. I didn't wet that part because it softened up the acrylic paint and I was afraid water would wash off the fuzziness.
This one is definitely not finished yet. I'm not sure where it's going to go, but it's looking for something to go into one of the corners without the gems. I'll show it again when it's finished.
