This canvas was covered like Kasha's below, using the back as the front to allow a window space. The wing of the owl lifts to reveal a nest. There is a discreet hanger attached on the back to allow almost flush hanging.
This canvas was covered on the front so I could use the back as a window, hence the back is the front and front is the back! Beeswax was applied all over to finish. The theme was fun and perfect for my dear friend Kasha.
