Working in another world-painting on an old “canvas”,
Another kind of painting in which I had the pleasure to participate involves using a 3” brush and no color mixing-no chance for “mud”-no use of expressive brushwork- In fact the smoother and flatter it is the better.
We are restoring one of the bedrooms in the family home. We had a wonderful artist re-plaster the ceiling and now we are working at saving the wallpaper (c 1888) and have repainted the floor. 
Now if only I had the $$$$ I would have the original oil paintings conserved as well before they are re-hung but this is a do it-yourself restoration and we will have to be content with what we can manage on our own.
