Two pieces of 5" by 5" fabric
A sewing machine
1/2 cup of rice
1. Cut your fabric 5 X 5
2. Place the fabric cute side to cute side.
3. Sew three of the four edges. Be sure to back stitch where you start and stop!
To warm them up, just pop them in the microwave for a short amount of time.
For a rainy day when the kids are saying "I'm bored. What can we do?" and they don't want to clean, cut some holes in a card board box, and have them toss them into it. :-)
These are on my Etsy shop if you would like to just purchase them. They are $5.00 for two hand warmers.
I hope you have a great day! :-)
