Ok, -10 and cold. I had to paint quickly as I dropped a wingnut off my easle and could not find it in the snow. I had no top clap and the wind was trying to get that panel off the easle. Anyway, I'm not trying to do paintings, only quick studies so all's well. I also don't care for exactness as I'm making things rather than trying to copy. This is 10 x 14 Oil On Panel.
I did learn not to leave my gloves in the trunk of the car overnight as the neoprene seems to hold cold as well as warmth. It took some time and cold fingers to warm them up.
