12 Degree Wedge Ruler help
 

Would any of you wonderful quilt ladies know the size of a 12 degree wedge ruler?

after spending some time on google, it looks like that ruler is only available with the pattern http://phillipsfiberart.danemcoweb.c...nd-with-wedge/
with a 12 degree ruler, it takes 30 pieces to make a circle. you could make your own template if you are comfortable with a protractor :)

The 12 degree ruler I have is 2 1/2" across the bottom, 8 1/2" on the sides & 3/4" across the top. Hope this helps.

Is 8 1/2" the exact measurement of the slanted side or is it 8 1/2" in a straight line from the edge of the bottom?
