ironing your patterns when finished with a project
Being a professional seamstress through the years,(retired now) learned a lot of things that worked and some that didn't. When a bride would bring me a pattern and fabric and all notions,I would return everything to her.Bridal gown patterns are huge when opened up,I always pressed them with an iron to get the wrinkles out of the pattern.and ironed them again when finished- pressing each time I folded them.When finished folding, it will go back into the original envelope,nice and flat, and then I pressed the whole thing , envelope and all. It works for all patterns.Time consuming,yes, but worth it in the long run.
