The design at right is made from the leaves of the sweet potato plant - just 2 separate leaves, pictured below. The folded leaf reminds me of the hearts I made in elementary school where you drew half the heart on a folded paper and cut it out.
The process: In Photoshop I carefully select the leaf from its background, that is the sometimes tedious part of my work. Then comes the fun part, I build separate patterns individually, and then put the designs into a larger design until it sings to me. And, I kid you not, when I get a good one the angels sing Hallelujah!
