Mounting a Watercolor Triptych on Cradled Art Boards

Wanna see how I make a watercolor triptych on cradled art boards? Watch the video below!

Each of these cradled art boards is 24"x18", making the finished size of the triptych painting 24"x54". These boards have a pre-primed paintable surface suitable for oils or acrylics, and a 1.5" deep cradled edge of clear wood that I stained and varnished a deep ebony color. After painting the triptych on 3 sheets of 24"x18" watercolor paper, I used acrylic gel medium to mount the paintings onto the boards. After the medium dried, I trimed the edges and sealed the painting using several coats of an archival, UV resistant, non-yellowing, acrylic varnish.
The result is a large watercolor triptych that can be hung and displayed without the use of frames, mats, or glass!

Here's how the finished painting looks, hanging on my studio wall!
