Hi, check on ebay. I recently got my 9 degree wedge ruler off of there for about half that including shipping. It was a set of 3 wedge rulers. I haven't done the spiral tablerunner but I am working on a circular bargello wall hanging for my son. They are cool to do with the wedge rulers. Also check on amazon too if you don't see what you want on ebay.
Thanks,
Sherryl
