Since the New Year will quickly be upon us, I thought I'd better get this post up for anyone who wants to go ahead and do this with me.
First up: Fabric. I decided to extend my range. I've got 28 fabrics. That's one for every 5 degrees from -30 through 110 degrees Fahrenheit. This might depend a bit on where you live and how many days a year you are in a certain range of temperatures. I'm working with fat quarters here, and if you go with strips that are 2.5" x 5.5" you should be able to (carefully) cut 28 pieces from each fat quarter. If you are in a temperate climate where everyday is in the 70's, maybe you want a fat quarter for each degree in that range. This is totally up to you and how you want to make your quilt look. If purple is your thing, you could assign each temperature range a purple color.
Lastly, the mini version: A finished center of 32" x 36" means patches would be cut at 1.5" x 3.5".
Some other things to mention. Each month (obviously) has a different number of days. I figure there are a couple ways of addressing this. If you look at my two examples above you'll see I added the extra grey patches on the right, starting each month on the same place on the left. If you wanted to center things you could add half patches on each end of the shorter months, or you could stagger your months, as well. I guess this might be less of a quilt-a-long and more of a suggestion/guide to get you going.
Temperature guide. I would suggest deciding before you begin to find a consistent place to base your daily temperatures on. If you want to use your own thermometer, great. I am going to use a website that tracks daily temperatures, and one that I can go back to find 'historical' data for when I'm out of town, or behind on my quilt (not like that would happen). In my case the closest weather station is an airport about 8 miles from my home. Around here, this matters. Since I am in SE Wisconsin, Lake Michigan can greatly effect the weather (called Lake Effect). But sometimes it depends just how close you are to the lake. Sometimes a half mile can make a difference in temperature and clouds and snow, too.
Right now, my plan is to share each week's progress on Fridays. Which means next Friday, 1/3/14 will have my first 3 patches cut and sewn.
Lastly, I am happy to answer any questions. I reply to comments if I can, but if you don't hear from me you are probably a 'no-reply' blogger. Then feel free to either leave me your email in the comment, or email me directly.
