Essential oil of choice
Cut out two 4 inch x 4 inch squares for every hand warmer desired.
Sew right sides of fabric together, leaving a few inches open on one side.
Turn fabric right side out.
In a medium bowl mix the flax seed with essential oil. Use three to five drops of oil for every cup of grain (this results in a pretty strongly scented hand warmer.) Mix and allow to sit for 5–10 minutes.
Use the grain to fill the hand warmers about ¾ full and then stitch it closed.
Heat hand warmers 25–30 seconds in the microwave, allow to sit for about 30 seconds and then place in pockets to warm your hands or in your slippers to warm your toes!
