Ugh!! I was doing so well on my 1st block but then made a mistake. Undoing has been impossible! I tried undoing stitch by stitch but couldn't undo the K1below correctly. I then tried to pick up a row of knits below the mistake and but when I redo it's not coming out right. I'm afraid I'm going to have to start all over again. This block was almost done! Hopefully it will look better in the morning.
i was worried about this, too, so i took the time to do a few stitches really slowly to try to understand what was going on with it. the stitch basically unravels and so you end up having to tink down to the lower stitch and then pick it up like you normally would with a crochet hook (or whatever). i think i get it, but am still nervous to have to put it into use if i mess up later in the square.
i wonder if Bernat would be kind enough to provide us with a video on how to pick up stitches with this...
