Snag Nab-It Stitch Catcher Tool by Dritz

The Snag Nab-it tool is used by many cross stitchers to help an errant stitch lay more nicely.  Simply run this needle through from front to back.  The little ridges in the needle will drag the loose bits through to the back.  Comes in its own little plastic sleeve to protect it while in your project bag.  2.5 inches long.
