I recently read an article in a sewing magazine about how to spot and correct pattern drafting errors in commercial patterns (and now I can’t remember the details and can’t find the article). The part that interested me had to do with front and back armhole depth measured vertically from shoulder to base of armhole. It said that the back depth should be longer (can’t recall if 0.5 or 1 inch longer) than the front depth, to keep the garment from sliding backward on the shoulders.
I have a pattern that slides back, and when I measure the armhole, the front and back depth are the same. So I’m thinking I should add to the back length in the armhole area. I remember the article said to add the length at the shoulder, but this will also add to the distance around the back neck, so that I’ll have to add to the collar, as well as the back slope of the sleeve to match the added length. But I don’t want a bigger back neck. How would I avoid that, while still solving the armhole problem?
Can anyone tell me what the correct adjustment should be? Also, did anyone else see the article? I think it would have been in Threads or Sew News, in 2006 before October. Or perhaps late 2005. I’ve checked out the article on pattern drafting erros in volume 125 of Threads, and that is not the same article as the one I’m interested in.
