get a drawing pin, and knot a string, ribbon or anything on it. You can put on 3, and barid them ,that would look cute too :)

stick the pin in the wall, tie another pin to the other end of the ribbon/string and stick that one to the wall too.
That's it. Now you can hang anything on it. The yellow thing is my ear stud holder, I clipped a hair clip to the string and then the ear stud thing :)
