Hi Kitty,
I believe we have been in many online classes over the years, including some on Quilt University with Joann Winn???
Your frustration came through loud and clear, but trust this old Lounge Lizard when I say, one has but to say something doesn't appear right on TQS and someone else with either tell us how to fix it, or do their best to help us figure out if it was our personal screw-up. While I've seen one or a half a discussion get a bit testy on TQS Forum, generally it isn't needed here.
I, too, would like an errata page, but sometimes, as we recall from Joann Winn's classes, that's tough to do because everyone reads online pages differently (I think). That's why Joann labelled her class notes by sections and paragraphs. Possibly this could be incorporated in future BOM instructions, but I doubt it would be feasible for this one...it's already done.
I think I'm just going to re-print in black and white. Generally, I've found this BOM to be very readable and do-able and just plan FUN!
