The knight of wands was SO tricky too! I decided to do a brave tree, sitting out on a road. The road symbolizes movement--the knight of wands is moving about so quickly and bravely that he often doesn't see where he is going. And he might be hit at any moment by a car, but he doesn't care!
I've finally gotten over my "painters block" concerning this deck. After much deliberation, I went with the standard page- knight-queen-king approach, but each of the trees will be older and wiser than the last. Anyways, here is the page of wands! Creativity and inspiration, through flowers and butterflies. A young tree, with much life ahead of her!
