Raymar Artist Supply makes a good quality canvas panel that I have been using. They also have an on-going art competition for paintings done on their panels. I submitted this painting I did of my son and it was chosen as a finalist for March. Each month a judge selects twelve paintings from those submitted that month as finalists. At the end of the year the top twelve for the year will be chosen for awards and a printed calendar. See the finalists here at Raymar along with the judge's critque.
