Cricut Expression..

So if you still don't know what a Cricut is here is a little video about what it is and what it does. It's cheesy I know, but it explains it.


Now for me to spend this kind of money on a craft machine I have to justify it by something (because $300 would also buy me a lot of other things too) and I thought about trying to Open an Etsy Shop. Problem is.. What the hell would I sell? I can also sew pretty well so I could incorporate that kind of stuff in their as well. I know my Etsy shop wouldn't just stick with one theme, it would probably be a mixture of a lot of stuff.
So my question to you is what should I try and sell if I got it?
