I've never seen a female shirt card. I think I'd elongate the card, round corners, and make it in pink and/or yellow -- that would be really feminine. Like the necklace idea -- it would be nice with pearls. The flower brooch is a nice touch.
My name is Lesley and I'm a craftoholic! Why spend time on housework when you can craft instead? A place to share some of my creations, if I can drag myself away from crafting long enough to post them!
