Here is a picture of some corn bags I made a few days ago. They work great as warm packs and you can even freeze them for ice packs. They are made from flannel material and shell corn. You heat them in the microwave for 2 1/2 minutes for this size. I will explain how to make them below.
Take a fat quarter made of flannel or 100% cotton material and fold it in half, them cut it in half to get two rectangles. Sew around the edges leaving an opening for turning and filling with shell corn. (Use shell corn that is not dusty and is clean.)
Fill the bag with 5 cups shell corn or you may use rice if desired. I like to use a canning funnel to fill my bags.
After filling the bag with corn or rice slip stitch the opening shut by hand or machine and enjoy. They keep their heat for a long time.
My husband bought me a Singer Featherweight 221 sewing machine for Christmas yaa...! I have been wanting one for a long time and wanted one in excellent condition. This one is perfect. I brought it to my sewing machine guy at the sewing center to get lubed and inspected before I started using her. I named her Fredricka after my late great-grandmother. I enjoyed sewing with her today. I love vintage machines. I am lucky also to have such a wonderful husband.
