I'm not sure if you're not finding something you like for free or if what you've found isn't transparent. If you're not aware, it's possible to transform clip art to transparent using Microsoft Word (I have an older version, but it's on the picture toolbar as "Set transparent color") by clicking on a white section. I haven't done this with a frame, but I've done it with lots of other google images. Hope this helps~
