What you need:
Fabric and flannel
1. Cut the size of fabric you want. Here are the sizes of mine: large was 17 x 6 and the small was 5 x 5.
2. I lined the bags with flannel to keep the heat it. I cut flannel pieces the same size as the fabric pieces.
3. I tried two different ways to sew the bags. For the large, I sewed the back sides together and turned inside out. The small, I put right sides together and zig-zagged together. Both worked well.
4. Leave a small hole to add the rice (use funnel if needed) and I added dried lavender. Lavender is light, pleasant and used to help with sleeping.
5. Lastly, I sewed the hole together.
The west coast doesn't get too cold so I might be sending a few mini packs to my nieces and nephew in Alberta. I'm sure they would love to warm up there hands and feet after playing in the snow on cold, winter day.
