This card uses a coloring technique I have never posted before. You use water based markers like Tombow markers as your paint on water color paper. You just apply the marker in the darkest areas and then using water and a brush blend out the color. It's takes some practice to master how much ink you need to put down and how much water to use to move the ink without moving it outside the lines but overall it's a very inexpensive technique.
I saw this technique done with ease years ago but could never quite get the ink to move correctly until I discovered that you need to use particular marker and paper combinations. If you don't have the right paper the marker will soak in and will not move well.
As always, click on the images for full directions including the stamps used and paper sizes.
