Does this count as a Purse, Bag or Wallet? I wasn't sure what else it would be. I designed the handwarmer pouch because my grandma asked for handwarmers for Christmas. She wanted them to stay on the back of her hand while driving. A search of the interwebs came up empty handed so I came up with my own idea. Basically it's your typical reheatable rice bag which goes into a cozy flannel pouch. The pouch is stays on the back of your hand with an elastic band, leaving your hands free for driving, typing, knitting, anything that makes your hands cold!
The pouch covers the hand nicely! It would still fit under a pair of big gloves or mittens though.

Here is the rice bag. There are channels so the rice doesn't move around.

And the back has elastic to keep it in place!

I was just thinking this pouch would probably fit chemical warmers too, Hot Hands is the brand I've seen at Wal-Mart. I like to use those when skiing so this would be the perfect way to keep it off the skin and in place!
If anyone is interested, I put together a tutorial while I was making this set for myself, which is posted on my blog here:
