I have to admit, I'm a sucker for a new ruler, but I have never purchased the Bonnie Hunter rulers. I've been so pleased with my Deb Tucker rulers; they work for most all the piecing situations I have come across. I admire anyone who can devise a new ruler, patterns, and marketing plan to go with it - that's what it's about, after all. I'd love to have that initiative! I would imagine there were discussions many years ago of " do we really need a big plastic ruler and a pizza cutter for fabric? I can just trace the templates and cut them out!" I'd say do whatever works for you!
