cloth : bad idea. Even if you know the size of your girlfriend's clothing ( too big- thinks she is fat; too small- doesn't understand her enough), she may not like the ones you buy and return them. result = waste of time
bread make : not as bad but still not good. I have one that I use occasionally and, let me tell you, too much work in getting the dough ready.
If I were you, I would save the $100 all together. Buy some color paper and fold a bottle of stars- if you can fold them fast enough, they are suprisingly suitable as a gift to give to a girl. You can count on my word for it
