The proposed project will consist of 12 11" x 14" framed works (measured 19" x 22" after framing*). I suggest hanging the work in 4 columns consisting of 3 works with equal spacing between each. I would also suggest the option of hanging in a single row though I am unsure of the available wall space per selected artist. 

*this is not rigid and I am very open to different ideas of presenting the work.
