Plays, I plan to do two rolls, the top roll high temps, bottom row low temps for each month. 1will start with the 1st to the 31st. I will have 2 1/2" squares. In months without a date, I will place a gray square. In between each month will be a 2 1/2'" strip of black. (Not 100% sure of the black strips, still debating). I figure it will be about 62" by 72" without borders. So far I have my temperature color guide and have picked out 23 pieces fabric (from stash). This next week I will cut out all my squares and start sewing. I have the data of temps for Jan and Feb. at the end of this week I will copy the March date and start sewing, to catch up. In my mind it looks neat, I'll wait and see at the end of the year.
