This grouping works because all the the frames are black & the subject matter doesn't have a lot of color either- also, the larger pieces are in the middle. I would have changed out that one brown mat though. Mats are fairly inexpensive to change- it's the framing that's costly. From Domino magazine
That frame in the far right, in the middle - landscape oriented and filled with cork board with a picture pinned on it. Genius! Children's art could be so easily changed out.
