Hi Melissa, from your neighbor in the Twin Cities...
I bought some fabric in a bag at a local thrift store. It had a couple of complete tops that needed to be sewn (my mother, bless her) loved one of them that I gave her for Xmas one year, and there was all this precut flannel. It was in all sorts of lengths but all cut to 4" width. It mattered not the color or placement. I sewed pieces together and when they were all about the same length, I sewed the strips totgether. I evened up the ends and proceeded to use John Flynn's method of attaching a back--you use the diagonal of the fabric and use a lot less. But I used one layer of off color flannel as the 'innards'. I used Eleanor Burns method of quick turn (all 4 sides sewn on the machine with a turn hole) and tied the thing. It might not be pretty, but it sure is warm!!
Personally, I think that flannel quilts are best unplanned. Flannel is a fabric that lends itself to leisure, and if you are fighting with it, it isn't leisure nor is it fun.
Stay warm. You have to be as cold as we are!! -14F is cold!!
