Marge, same here and now I am finding out many,many things I never knew :D
You can make your own. The Moda line makes them. They are the width of the fabric (usually 45 in) and you cut them in 2 inch strips.
I was thinking of making some too. I've bought them and they are so much fun to work with. You can make as many as you wish. I think Moda's are 40 strips- something like that. Joann's also has them but I haven't bought any.
