Last year, I got one of these for Christmas. I had seen it on Pintrest, so it already was on my, “when I can get to it” list. A friend saw it when I delivered a casserole to a funeral dinner recently. She wants written directions on how to make one as a Christmas gift. If I am going to write a pattern, I might as well write an Instructable while I am at it. So here is how to make your own 9”x 13” Casserole Warmer/Carrier.
