If you're like me, and working on fabric, choose your preferred colors of iron-on vinyl. I've heard good things about the Cricut product, but like I mentioned already, there are less expensive options for vinyl products too, especially if all you're doing is free-handing your design and not needing to run it through a cutting machine.
