I have never made or used the rice bags, but I hear they are
wonderful. I did make about 30 corn bags last year as Christmas gifts. They are not a very exciting gift, UNTIL you need them and then are priceless. My husband just went
to the grain elevator and bought a couple of 5 gal. buckets of
corn. It's not expensive. Mine were larger than the rice
bags and I made pillow cases for each. Had a daughter do
machine applique of "His" or "Hers" . I've used mine many, many times
and they can be put in the microwave or freezer, depending
on which you need.
