Wow Ck! You're on a roll. Congratulations on using so much stash. My 2017 temp quilt will also be quite large, if I ever get the borders and key put on it. I think that's the nature of the beast, unless you do them the way some of the first ones I saw were done- those were not quite so large. Some of the first ones I saw did high temp for each week instead of each day.
