She wants it to have a diamond in it, and then some frilly detail that will offer up plenty of opportunity to cover it with sparklies. The first one here is me playing around, and is probably to detailed to be the best choice for a functional graphic.
To be honest, I don't think that any of these will make the cut, but they could be used as secondary design for shirts, etc. I don't think of these as a waste, the process of making these is what I really get out of it. It's a way to see "OK, this line works here, and this curve works there." And besides the possibility of being used later for something else, it is yet another something to show people that want to see my style, as well as can serve as a springboard for future visual concepts.
