I'd really like to make some of the quilts that use the long degree rulers - some of these are the asterisk quilt designs. The degree rulers are pretty expensive on their own. I've read a few blogs where the blogger has made their own ruler/template. I could do that - but how do i get my specific degree shape - like 15* or 9* etc. I'm sure this is a pretty easy answer and one of those I'll go - yeah, that makes sense! Can you help me out with this please?

Thanks !!!
