and this last comment by Barb is why I make Kilts with a machine to my method and have never taken Barb's course.
If there are 12 students Barb would never get around to teaching the others because she would have to stand over me constantly with a big stick. The other would get annoyed by the sound of whacking. And Barbs voice would get louder and louder and higher pitched as she repeatedly said "NO STEVE! That's not right. Rip it out and do it right."
She writes books and writes books and some of us just sit on the floor chewing on the covers.
