1. I cut off the front at just below waist level, making sure I left a bit extra around the side seams.
It's not perfectly neat, but I want this to look a bit distressed, anyway.
3. Moving onto the back, I want it to have tails, so I slit it down the middle of the back. I folded it in half and cut along the middle.
The picture refuses to go the right way up!
4. Hem the back the same way as you did the front.
5. Now you need some oversized buttons. Sew them onto the back at about lower back height, or wherever you want them.
and there is is! The knitted tailcoat!
You can add more trim to the front if you like, like buttons or fake lapels, but I decided I wanted mine simple. I am wearing now as I type on the computer. If I was going out I would probably wear my clockwinder necklace with it, which would add detail.
