I have been keeping records of Highs and Lows. Choose a batik jelly roll and divided the colors and temps in 5 degree increments. I put each color in its own baggie with a sticky note indicating the temp. Then the process just sat on my sewing table. Well, yesterday I started on January and I like the results. I chose a super simple 2.5 cut for low and high, sew together. Then stack with day one on the bottom and move to the top. I think I will divide with narrow black strips. No photo yet. I will post when I get a couple of months ready for viewing.
