Sketching outside below 50 degrees is uncomfortable, but it's nearly impossible under 40 degrees.
I thought I was prepared for sketching the Mayday parade today - warm winter clothes, fingerless glove and folding chair. But the 39 degrees ( felt like 30 degrees with the wind) weather was too much for me.
I had to leave before I could see the parade. I sketched the very cold crowd.
Better luck next year.
