I absolutely love Amy’s technique, it’s so much easier than using a crochet hook (at least for me, anyway), however, I am having problems with the 1st CO st. I tried tying the scrap yarn and working yarn in a knot, as Amy did in the video, but when I knit the 1st row, the last st in the row (the 1st CO st) keeps falling off the needle, or it is very loose. I also tried not tying the yarns and letting them hang from the needle, but after the CO was done, the yarn started to fall of the needle and the CO edge unraveled. I also tried tying the scrap and working yarns together in a slip knot, then undoing it a couple rows in. That caused a knot in the corner of the piece, and the k and p sts that go up from the 1st CO st got lost.
How can I connect the scrap and working yarns together when I start the CO so they don’t fall off the needle and the CO doesn’t unravel, and not create a knot in the piece?
