I bought two pairs of lightweight wide leg trousers which are about 3 inches too long. They are meant to be a shorter size already so I had hoped to avoid this situation. My lovely dm would usually shorten them for me but she’s really poorly so I don’t want to ask her. As I want to start wearing them, I’m thinking of trying to shorten them myself but have no idea how to start. I can borrow a sewing machine but, beyond that step, I’m stumped.
