I hate to say it, but I agree as well with only $1-2. I know they probably take time and effort, but they look similar to hairclips that you can get at any old store, wherein you can get, say, a set of 10 for 3 or 5 bucks. If you made something more unique, rather, you could probably get some sales.
Try to find ways to make them more appealing to a cosplayer or an anime fan. Something maybe with cute beads or an extravagant bow. Maybe something mimicking an accessory that a character wears. There are many people that sell other lolita items, cat ears, and many booths sell jewelry from popular anime (Naruto, Nana, etc) so that's out of the question unless you can compete with the quality but remain at a down-to-earth price.

Oh, one idea I got a while back was like... There were these odd moogle band thingies in KH: CoM that looked fairly simple, and I'm sure people would like them. Not sure if this'll fall in your line of... uh... making things, but... I'll try to find a picture.
