Touchstone has been a prominent artist-owned gallery since 1976. In 1996, the gallery moved to an elegant and spacious location in the 7th Street Arts District of downtown Washington. There is an active art scene here, with several exhibition spaces in the immediate area and five other galleries in the 406 7th Street building itself.

Touchstone is open Wednesday through Sunday and has an average of 400 visitors each month.

The gallery maintains an active membership of 35 to 40 artists. This number provides a diversity of artistic expression and personalities, yet allows ample exhibition space for each artist.
