They are the best. They have the knowledge and the "eye" to pick the best elements to use for framing artworks. In some cases they have restored and reused the original frames we had because they were chosen by the artist and decorated by him. They did a wonderful job each time. We have never used the DIY option (because we are lazy) but I'll keep it in mind for straightforward things.
I'd be hard-pressed to find another shop--of any kind--in DC with a friendlier, more relaxed, and personal, small-town atmosphere. We've been customers here for years and have brought countless projects, always with stellar results. However large or small he project, the terrific staff always give their full attention and sage advice.
