I recently had surgery and have a cast on my right arm…and it gets VERY itchy after a week or so.  Chopsticks and knitting needles are all too short…but a small magnet tucked into the underside of the cast and then ‘dragged’ along by a larger magnet was a great way to scratch those hard to reach spots.  The workcover people think it’s a fantastic idea!!  :-)

Brilliant…!
