My first quilt I made my mother cut a cardboard square for me to use as a template for my blocks that I traced and cut out with scissors. I still have it.
I had a few friends ask me to teach a beginners class, I was thinking of doing the same thing. very minimal investment. Learn to line up a 1/4 seam from the markings on the needle-plate. I figure if someone is hooked they will want to learn more and be willing to invest some more.
