craftgrrl | This is a CRY FOR OPINION, not selling...

I was wondering if anyone could give me a "ballpark" figure on how much "fake hair" kinds of things go for?
I am making my own "fake hair" barrettees and was wondering what to charge for them... PLEASE keep in mind that these are not "falls" or anything like them - these creations are unique "odd clips"' meaning that I am not trying to "copy" anything I've seen before, but trying to make something completely different.
here's a "practice page" with a pic of four of them.. they're about sixteen inches long..

Any help would be most appreciated!
