I've seen these on-line, at a specialty store that I can't remember the name of and at Amazon, and have decided to make one for my Dad with some items I already have. I figure if he likes it and uses it I will purchase one. They're a 'muff', like you might use in the winter, that the person can put his/her hands in. Inside might be a squeeze ball to keep the hands occupied. There are also other gadgets/items sewn around the bag to keep the hands and fingers busy so the person isn't constantly picking at his/her hands, fiddling with other things, etc. Does anyone have one of these and does it work?
