I know that there will be 10 wedges at 9 degrees and 9 wedges at 10 degrees in a 90 degree angle, which is one quarter of a circle and I have a paper template but I don't know how long the rulers are, how wide at the bottom/top....that is all I need to know...I ordered my pattern last night so when I get it, the instructions may help me figure it out, but if anyone can tell me the measurements for the 2 rulers, I would appreciate it...
