I have a newer copy. I don't think I found errors - it's more "omissions" I added a lot of notes to my copy for items that I felt should be there and aren't.
The part that almost tripped me up big time - on the back is says you need X number of 2" strips. But you don't use any 2" strips, they are all cut at 1.5". I almost started cutting a bunch of 2" strips from my larger pieces - and I'd have been very upset to then recut them and have that waste. And it's got a few places with 1" strips, but there is only one place they are needed. If I make it again, I'll adjust so I don't have any narrow strips. I don't think they add anything other than increase the "pain" factor.
I think this was a real fun quilt to make.
