I got a t-shirt in New York in a child’s size because it was cheaper and fits fine apart from the neckline which is a bit tight and I would prefer it in a V-neck. So I decided to re cut the neckline. I could have created a new collar from spare jersey but I decided to use the original collar. So here’s what to do:
- Unpick the neckline at the front
- Cut the neckline into a V shape (don’t cut the collar)
- Stretch the collar as much as possible
- Reattached the collar to the new neckline


As you can see the result isn’t as smooth as the original collar because the jersey is being stretched but I quite like that.
