I might use a drag knife if I find one that looks promising, and if I’m cutting in thinner materials like paper or vellum. I also plan to add a laser down the road at some point. But with something like the x-carve, I could even cut stencils out of thin woods, like bass or balsa, maybe plywood underlayment, and they would be far more durable and reusable in cases of designs I wanted to be able to replicate. The Cricut looks neat, but nowhere near as versatile. And stencils are just one goal. I have lots of woodworking projects in mind, of course! 
More than anything, I just want to see if anyone else has done similar stuff and has pics they want to share! I’ve been getting lots of inspiration from the forums.
