I dug out one of mine and cut a couple strips, folded them over and stitched around the edges. Then folded them one inside the other and stitched them to my page so that they made staggered flaps that lift up. Added the word "under" to the flaps, drew a vine, cut leaves and circles from more under paper, did a bunch more doodling and called it done.
The background is book text with a watercolor wash, then less watery drops blown around with a straw. Bit of shading in the corners with gel sticks. I quite like the look of this one. Kept adding tendrils to the vine until it looked full enough to me. I tend to stop too soon on things like that so they always look sparse to me later, but I like this one.
