What you need:
-felt/wool/fleece (I used scraps of felt from another project. An old or worn out sweater or blanket would be another great option.)
-needle and thread
Cut fabric into reasonable size pieces. I cut mine into circles 2 3/4 inches in diameter. Sew two together along the edges leaving a gap of about an inch.
Carefully pour 1-2 tsp of rice into the packet. Sew the gap shut and tie.To use:
Warm in microwave/oven/toaster oven. If using an oven or toaster oven, lay on the rack. Place into pockets, gloves, boots, slippers or anywhere else for extra warmth. Great for waiting for the bus, watching outdoor sporting events, engaging in winter sports, walking in cold weather, etc. No chemicals and no disposal.
It's so easy. Once they've warmed up, they hold their heat well. I recommend them.
What have you done to combat the cold weather?
