quiltsRfun, totally agree w/ you.
She has never said the rulers were mandatory, she even includes instructions on how to do the units w/o "her" rulers. She doesn't even charge for the mystery (quite a few out there do). Sit back enjoy the scenic route this year. No matter what order we do the units we were always going to have to make more triangle in square blocks, at least this way the technique you perfected the first time is still fresh in your mind.
