What does the field think about a small pocket at the foot end of an UQ that would hold a hand/toe warmer? Talking like a 3x4 piece of stiched material to just plop one in there. Figure it might help when first getting in and through the night where there is less actual body contact to help warm the down.
And if its a decent idea, where would you put it? Just one in the middle, or maybe two pockets on either side, at about 1/3 and 2/3, in order to account for your feet laying diagonal across the UQ towards one side or the other?
Better ideas? Not looking for a substitute for the hot water bottle thing, just something for folks with cold feet like me.
