Curious how important finishing touches, after the painting is done, is to the eventual sale or no-sale? I'm referring to painting all canvas edges the same color (I've been using a custom mixed dark gray), signing the back as well as the front, adding the paintings' name to the back, certificate of authenticity and/or artists statement to the back... those type of things. I'm restarting outdoor art sales this weekend, and after a few months off to build up inventory I have 51 new canvas pieces to consider, some as large as 60"x48". Painting the edges on all of these alone is a full 2-day project. If buyers percieve a high value to all of these things, I'll do them.
