I have tried using the turned interfacing method, but found it didn’t work well when turning inside corners on a shape. It was a maple leaf. Perhaps I was doing it wrong? I think it would be great if there were only outside turns and corners. Even though it’s just a table runner, I still plan on embellishing with quilting so I need a needle to be able to go through whatever fusible I would use. I think I’ll just turn the edges because in the end I’ll be happier and less worried about it.
