These roses were in celebration of my friend Mary's birthday, and I have wanted to paint them ever since; however, roses are a daunting subject. These were white, but had a surprising amount of green in them. I was going to paint the other day and got as far as putting the canvas on the easel, but had so many interruptions that I didn't get back to it until today, two days later. It gave me a long time to think about whether I was doing the right thing in painting on a black canvas. Today I plunged right in, and I am really happy with the result.
