I saw something on Craft magazine that had me intrigued. I, of the perpetually cold feet, needed something to warm up the bed without a wasteful blanket heater (because I always forget to turn it off although the cats love it).
It was a Cozy Bed Warmer that used corn feed from the Pet & Feed store and a bit of fabric.
Well, I have excess fabric in spades, and I always make a trip to our local Pet & Feed Store to pick up food for the cats. On my last trip, I picked up some whole corn feed (about 3-4 lbs) which is incredibly cheap. Then I took some scrap muslin and made myself a Cozy Bed Warmer. I didn't feel the need to make it out of fancier fabric because a) it's not a gift and b) I'm going for functionality and ease of making. Trim? I don't need no stinking trim! Plus muslin was the most copious and easily readible fabric in my whole stash (plus I have quite a bit left over from various mockups)
With cutting and sewing, it took maybe 8 minutes top on the sewing machine.
Love, love, love this thing. It goes into the microwave for about 3 minutes (while I'm brushing my teeth, etc) then gets shoved in under the covers just as I crawl into bed.
It stays warm an incredibly *long* time, and (not) surprisingly, with my feet warm, the rest of me isn't as cold. And of course, the cats love it, and they have a tendency to sleep around my feet now. I can also see using it as a nice warm heating pad for aching muscles.
If I make any more to give as gifts, I'll definitely be using much nicer fabric than my plain muslin, as well as some trim :-)
