I have made too many buttonholes in 1/1 ribbing. Is it possible to close some of them neatly?
Welcome to the forum!
Probably the neatest solution is to mark the place of the correct buttonholes then rip back to the buttonhole row and re-do only the ones you need.
Depending on the type buttonhole made, you can try grafting the two edges together but it’s not going to be as clean a fix as just re-doing. Maybe worth a try since this method can be easily undone if you don’t like the look.
