Fixing a dropped stitch isn’t a new thing in machine knitting but knowing at least a couple ways to rescue dropped stitches is helpful.
In one of the two methods shown, Helen uses the single stitch transfer tool to first hang the active loop and all dropped stitch bars onto the machine needle above. The the next stitch bar is located for the next stitch to repair and before corrected, all the other bars are then allowed to hang free so that one by one, each bar is worked back into a stitch until all dropped stitches are re-worked.
The other method shown uses a latch hook tool held from the top down that similar to how we correct dropped circular sock machine stitches. I imagine a dropped ribber stitch (not shown here) can be latched from the bottom up (like on a circular sock machine)?
