Two things helped considerably. First was the theory that a pillow would help insulate my backside as I sat on the slats of the garden bench. Second was my wife's Mountain Guide Full-Flap Hat from L.L.Bean.
This item is not only well-insulated but also has Goretex to cut the wind. (Short story: This was to be my hat, but even a Large doesn't fit, so I gave it to Trina. She always said I have a big head. Now I have an X-Large on order. Some might think the classier Mad Bomber Hat might be more appropriate for this kind of painting, but I don't like the rabbit fur.)
I was comfortable in the 30 minutes I sat to paint this piece - even though the wind was not only whipping up whitecaps but also knocking my paintbox about.
