I have learned the Vikkel Braid trim ! I am so excited !
I found the instruction on YouTube, and learned also that Nancy Bush’s book “Folk Knitting In Estonia” has Vikkel braid finishes in her pattens. (I must get this book !)
I did the first row after a long-tail cast-on with the Vikkel Braid, then after my rib/moss border, I did another Vikkel. The really exciting thing is that the bind-off method I use matches , so I can have the cast-on edge look like the bind-off edge. And it’s stretchy too. This shall among my signature edgings !
