Hmmm I'm a bit stumped. I'd have to say they probably would not count, unless they match the list of what is listed. This particular challenge only allows for brads, ribbon, doodles, paper and a a journal spot. IF they fit in somehow with one of those "things" I'd say yes they work. Or if they are extractions from your own photos that somehow go with the theme of the page - then they'd work too. If they look like doodles, they'd work fine here.
Link us up we'll see how it works.
If nothing else we'll certainly still leave loving on your layout.
