A frame should finish a piece without speaking over it. For Tidelines I kept to three: a pale floating frame for the brighter works, a warm walnut for the pieces with more earth in them, and a simple white frame with a mat for the two that are mostly photograph.
The test is easy to describe and slow to do. I lean the finished work against the wall, set a corner sample on it, and walk away. If I notice the frame first when I come back, it is wrong. If the painting looks slightly more itself, it is right.
Floating frames suit the works where paint runs to the edge of the canvas, because they keep that edge visible. Mats suit the quieter pieces. They give the eye a moment of white before the photograph begins.
Every original leaves the studio framed and ready to hang. If you would rather choose your own, ask before it ships and I will send it unframed, with notes on the edges and a few frame suggestions that suit the piece and your room.
