Circuit or sizzle.
 

What are the differences between these..
Thank you

Cricut is a digital cutting machine. You can purchase design files on the internet, so sky is the limit. Svg is a common cutting file. Sizzix is a cutting machine that you use dies to cut your shapes.

Factor the materials you want to cut. Fabric, paper, vinyl, or card stock? What projects do you want to do?

I think there are different models within Cricuit ... what does each one do (or not do!)?
