What do you do if you start painting and part way through find that your subject matter doesn’t fit your canvas? You can always start over, but this can be discouraging. Another option, if you are painting on panel, is to extend the panel by bolting on another section.
One of my classmates had exactly this problem and Gary thought it would be a teachable moment, so I volunteered to help make and attach a custom cradled panel section.
Making the miter cuts for the corners of the frame.
Clamps hold the frame true and flat as the glue dries. I used Gorilla Glue and made sure to drill and countersink the mounting screws before assembly.
Here’s a view of the back side of the finished frame. The new section is visible on the left side. I was happy that I was able to get a good strong joint that yielded a rigid and almost seamless painting surface.
Here’s the finished frame, awaiting paint. The crack on the front is very small and will hopefully disappear as layers of paint are applied.
