Dear Pam,
I've never worked with a gallery, so my thoughts are worth as much as my gallery experience
I do agree that you should have a cohesive appearance to all your gallery art, so that compatibility of frame design is important, since I would presume a gallery would group your work together on a wall. It's impossilbe to guess at what a buyer's taste is... of course there are many artists who feel no is better qualified than the artist hiself to select a frame.
I don't consider myself paricularly good at framing, and I don't
want to become good at it.
I have had consisitenly excellent experiences with

The frames do not show a mitered seam, which I think makes them look much more expensive than they are; I always order the extra depth, so that the frame sits flush on the wall when it is hung, rather than canting forward.
Good luck, see you soon!
