Hmm,in her printed patterns she always includes printed versions of the rulers so you could make cardboard templates. Sounds like this is not the case for the BOM. I will say that her drunkard's path templates are really nice because both curves are set up as "outies" making it very easy to cut, but you need to follow the instructions.
I would see if I could borrow some, or buddy up with someone & you buy one template she buys the other...
