What Should I Do With This?

I mean that title quite literally. I found these cards while I was out looking for paper one day, and I couldn't leave them there. They were very reasonably priced and too cute not to pick up. I knew they were destined for my shop. And now that I have them, I'm not sure what in the world to do with them. There are 8 flat, scalloped cards and I don't want to just play around on one of them like I might with a regular rectangular card that I could easily make more of in case I mess it up and make it unusable.

So, I'm asking for suggestions. What should I do with this? Anyone? Oh, and bear in mind that I don't have a scallop punch, which makes things a little more challenging.
