Some people use rice for the filler, but it doesn't heat as nicely and starts to smell funny over time, which is why I opt for the corn or beans. To buy cheap, dried corn, just go to a feed store for small amounts or a tractor supply store for large quantities.
- I like to use the dried herbs in the socks to be used for a heat pack, because it makes it smell nice when heated. The ones to be used as a cold pack won't really smell so it doesn't matter as much in them.
- If you're concerned about keeping the pack clean, you can now place a second sock on top of the pack you've just made, and remove it to wash as necessary.
- When I made these originally, this is the point I stopped at. But recently I ended up deciding to go back and add in three straight seam lines, which breaks each tube sock up into four compartments of corn. The reason I did this is so that the corn stays equally spread when it's draped around something (like a neck, arm, etc.) instead of all the corn going to one end. If you do this, be sure to use a zigzag stitch to accomidate for stretch. Also, don't sew ALL the way to the end or it will poke out a little. It's ok if a piece or two of corn moves around, you're just putting the line across most of it so that ALL the corn isn't flopping around.
