I lived in a loft in Emeryville CA a while back. Taking full advantage of the space I did some big paintings including a series of chairs. Trying to stretch something of that size was impossible for me. A canvas needs to be as tight as a drum or it will give too much under brush pressure. Fortunately there is an excellent canvas builder in Oakland called "Rubars" who made my canvases. I have no recollection of what it cost but I'm guessing $300. "One" was the first of the chair series. I did five back then, another two years later, and I'll probably keep doing them. Acrylic on canvas, 72" by 60".
