Hi and welcome back! I pulled out some paint markers that I bought at Target quite awhile ago. The paint is very thin and smooth. I thought that the paint would be a resist, so I swiped Mermaid Lagoon Distress ink over the red bird to make a blue background and Fossilized Amber Oxide ink over the blue bird, but the paint did not resist that well. But since these were paint pens, I was able to paint the birds again so that they really showed up.
I found some fun backgrounds in my stash to add the birds onto. The background with the red bird was made by taking out the cap with the long tube on it from some inks sprays and using the tube to make circles on the already wet watercolor paper. The blue bird's background was made by stamping a background stamp onto black card stock using White Brilliance ink.
