This is a tough one! I even tried some of the trim work in my sister-in-law's kitchen, but ultimately decided that this leaf is the most symmetrical. My niece, Rachel, was even trying to help me find some things to take pictures of. I think that had more to do with the fact that she wanted to go back to playing with my camera - she is saving her money for a good camera and was checking mine out. She got some great shots!
