I have a question I can’t find the answer for with Google and the PR boards/knowledge base. The answer is not in David Page Coffin’s book on trousers (more a man’s view on waistbands) or in “Pants for real people” (only advertising a certain interfacing). So I’m trying my readers: I have used a straight waistband on a pair of trousers, but want to change this to a shaped waistband. Is there a special method to change this? Anything to take into account to change? Or can I take the pattern pieces for a shaped waistband from another pattern and use that? Simply something I haven’t done before. Thanks for your thoughts/ideas in advance.
