I wanted to try a Vaseline Resist technique , but it needed fluid watercolors, which I don't have. I tried it with acrylic paint and it didn't work with the more detailed stamp I wanted to use. But I decided to use a variety of different green mediums over it for a "Variegated Verdant" background.
Adhered dictionary pages over card stock and tore the edges. Stamped an image with vaseline then painted over with green acrylic paint and rubbed the acrylic paint off the vaseline (it just looks a bit streaky). Covered with peeled paint Distress Stain and let dry.
