How to undo stitches in the round

    Maybe you've forgotten where you're at in a pattern, or the number of stitches in 
the round doesn't match the pattern, or you simply think your crochet piece could 
look better. 
    Whatever the reason, it's very easy to undo crochet stitches, and if you use a stitch 
marker to mark your rounds, it's also easy to troubleshoot as well.

TIPS:        
   When you first feel a stitch coming undone, you’ll probably be left with at least two loops. This means you haven’t undone the whole stitch yet! Keep pulling until you only have one loop left. That loop should come out of the stitch you want to keep.
