I make my frames myself from rough-sawn timber. I mostly use Ash and Oak, but I made three larger frames in Walnut for a recent project. The images to be framed are closeups of green plants and the work is titled “Photosynthesis”. The frames include veneered panels on the sides, and they have three recesses with two extra vertical profiles. The centered profiles are joined with the horizontal pieces with a mortise and tenon joint, the rabbet making it quite a complex joint to make.
