Surprisingly, I use about the same amount of thread every year. In 2015, I used 23 spools, slightly more than my average of 21. I know this is a flimsy measurement. My spools are different sizes, I don't start the new year with all new spools, and hand sewing uses less thread than machine sewing. But I like to toss my empty spools in a basket throughout the year, then see how many I have at year end before tossing them out. Yes, they're all Coats & Clark's Dual Duty. The basket's empty now, ready for the new year. I hope you have a lot of quilting fun this year!
