CASology is pond. So, I went with one of my favorite pond plants, cattails. I used the Stampin' Up Inspired by Nature to stamp the grass with green ink and a brown Bic Marker to hand draw the cattail tops. I used a white colored pencil to add highlights to the cattails. For the pond water I rubbed on Sky Blue Metallic Rub-Ons and added highlight with a white American Crafts marker.
