For any of you who made or will make the rice-filled foot warmers for which I previously gave directions, here's a follow-up tip:
Be sure and double-stitch the seams. If your bag is already made and in use, you can use your machine to sew around the bag, close to the previous seam, being careful to keep rice grains out of the way. Use a strong thread and a tight stitch.
I accidentally ran a finger through one of my seams and could have had rice all through my bed if I hadn't noticed my initial puncture.
A word to the wise…
