I use this technique so often I just assume everyone knows how it’s done, but every month several people need to see it demonstrated again. (Trust me, it eventually becomes second nature!) Sometimes called a “one-hole bow” (although it’s not a bow), this technique ensures that the ribbon doesn’t slide around your project. And because it’s only tied once, the knot is less bulky than a conventional one.
I wrote a tutorial on this three years ago here. I hope you try this out!
