Pretty Warm Designs Stitch Fixers
These hooks should be in every knitter's bag. They provide a way to fix cables and lace stitch errors, as well as snags in your favourite knitted sweaters. These are suitable for heavier yarns from worsted to chunky/bulky.
Dropped stitches are simple to fix, by slipping the hook into the stitch and pulling the upper yarn strand through the hooked stitch.
