what can i do with ..... ?

another question..




ok so a friend gave me these butterfly vellum die cutout.
see here:



problem is = I DONT KNOW WHAT TO DO WITH THEM!

i was going to make a mobile but the backside of them is all fuzzy and white. so the back shouldnt really be seen. i dont wanna just stick them on a window because i think the back would take away from their color. and i dont know what exactly "vellum" is but they seem impossible to decoupage.

any suggestions on what i can craftily do with them?
help help help!
thanks!
