Thinking outside the frame

"Evaporation, flow study #7,'' by Patty Stone, at the Brookline (Mass.) Arts Center group show "Unframed,'' June 15-July 20.   The show displays unframed art work  on paper. The gallery says that "Each piece is purposely displayed directly on the gallery wall, allowing a more thorough exploration of each piece. 'Expanding and releasing the paper from its constraining structure often creates visual, as well as structural problems within the work,' said Elaine Sapochetti, one of the artists  in the exhibition. 'Yet, challenging these restrictions also makes the development of the art endlessly exhilarating and the completed work always a surprise. Just as in life, pushing boundaries can frequently lead to new, complicated, exciting, and inspiring revelations."'
