Daily paintings can be recreated as an original painting in any size.
The above paintings are each 16" x 16" on 2" thick cradled maple panels for self hanging. The sides of each are painted so there's no need for framing. 

Below is a commission, the client specified the size, 30" x 70", but left the rest up
to me. I began the process with a sketch (see below). Upon approval, I stretched the custom sized canvas using heavy duty, professional maple stretcher bars
handmade in Maine.   

10% scale - painted sketch for client approval.
