Long before I learned to quilt I decided to make 50 warmers very quickly for gifts. I found knee high athletic white socks for $1.00 a pair. Went to feed store to purchase large bag of deer corn. One lady used funnel to put the corn in the sock, while another person sewed across the top of the sock. Took 25 pair to make 50.
Later when making prettier warmers I used a decorative pair of socks. One as described above & pulled the other sock over the stitched end, tied with a pretty ribbon. The outer cover then was easy to throw into the wash to keep a clean fresh look!
