I completely understand this frustration. Fortunately, I am kind of a math lover. I can sit with my calculator and graph paper figuring out things for hours. Whether they get done or not is a different story! I've been working at "publishing" my original patterns and one of the latest ones was a large lap size in the original. I felt compelled to figure it all out in four different sizes before going ahead and listing it. All the money that is spent on books and patterns - not to mention fabric and supplies - should surely offer some personal choice options.
