On the subject of Masonite; the fact that it breaks if dropped just a few inches is a concern. And the fact that it warps easily in humid conditions makes it unstable for art.
The reason why canvas is the all around best is it's flexibility.
Silk and cotton fabric with tight weave on one side of the scale to burlap(Guaguin) on the other side.
I'm still kind of new to painting so just wondering what others think about this. I have tried watercolor paper, which i like to paint on, but i figure that people are not going to pay much for an acrylic painting on watercolor paper. Have also tried masonite, but the 1/8 inch thick seems to chip easily and the thicker boards seem like they would be difficult to frame. Are there other options i should try?
