Context: I have a dress with a long slit in the side. I decided to ad some corseting, so to speak. I’m an amateur so instead of thinking “get a tool and do it right”, I decided to cut diamond shaped holes. Well they’re bigger than I wanted and the material is chiffon over a cotton/polyester blend.
What can I do to clean up the rough edges of the holes and make them look a bit more decent without going too drastic?
