By 'painting surface' do you mean canvas on splints or is there some pretreatment to the canvas before the real painting. Can you post one or two of your pictures. Would love to see them. Your little greenhouse, if that is the little building your husband (?) is standing next to looks pretty fancy. Your weather is very similar to ours sounds like. Frustrating when it is so lovely during the day and then down below freezing at night.
