3 pictures in a row can help to better anchor a gallery wall.
This set of three is on a huge expanse of wall, and fills it without making it feel cluttered.
This grouping is taken all the way to the floor and makes the wall a little more interesting.
This isn't a straight forward grouping of threes, but by adding a center point to two pairs of prints, you can get the same effect.
I love this triptich from Gray Malin. How fun would this be in a kitchen or dining room?
Do you prefer hanging things in 3's? Pairs? Other? Let me know!
