@Clairibee - I've been familiar with that technique for quite a while, but since you mentioned it I rewatched masha's video. OMG I have been totally missing that second part where she explains how to do it with strings that aren't the same color(like in this pattern). When I watched it first I scanned it too fast and thought that you add a strand to both edges AND you ended up seeing these in the pattern. I was wrong and now I see that's how you get nice edges like in your version of this pattern. Thanks for pointing me back in that direction!
