Backgrounds - Acrylic Resist

I can't take credit for this technique, I learned it at Cornerstone, my favorite stamp store.

To create this effect, I painted broad strokes of one or two colors of cheap acrylic paints onto various papers. How much white space you leave changes the end result. After the paint was dry, I sponged on some dye reinkers to fill in the rest of the space, wiping the excess off with a paper towel. The paint resists the reinker, and gives a brush stroked background.

Here are some samples...
