A friend in Australia hand made a blanket for me earlier this year. She’s a science geek. Since, in the mountains, temps go down about 37 degrees every night throughout the year, I’ve been using this blanket throughout the Summer. It’s super light, just lots of air in the midst of a very loose stitch. It’s double layered. Lot’s of air. That’s a good use of thermo-dynamic technology. In looking at the huge spaces between stitches you would never think it could possibly hold that much heat, but it does. But there’s more. She used the golden ratio and the Fibonacci sequence. I feel smarter just throwing this over myself.
