I made one. Double sided flannel with warm and natural batting. It is 120 X 126 inches big. Yep, an oversized king, and it could have been ten inches bigger. It seems I only get less than half with the three of us, my puppies loves it too. Anyways, it is as warm if not warmer than my $600 down comforter. And to boot, it only cost about $75 to make. Got the flannel for a $1.49 a yard and the batting for $6 dollars. I plan to make more as presents.
