I can't tell you how good that is to know. I will have to see some to fully understand the look of it. I have a ton of these art boards my mom left me so it's good to know this. Thank you ever so much. I've done some lighter paintings on them. I'll have to experiment.
Cradlebord can have a 1/2 to 2 inch side with the top surface being a variety of hard bords to clayboard surfaces. Thay are great to work on. The color pops and you can build up pigment in ways that are not practicle with canvas. One of the reasons the color pops is that on boeard, pigmants are not absorbed and dulled when spread on canvas.
