I think that I once read of a technique to transfer designs from regular printer (or was it copier) paper onto fabric. Does anyone know if this works and how permanent it is?

I want to use a fabric pen on my bluejeans, but I'm afriad to freehand it. I was hoping to use the printer to get the right design, and then trace it with the fabric pen. If you have any idea how to do this, I'd love to hear. TIA.
