Reusing art is actually pretty difficult.  Sometimes there are meanings associated with the piece used that have to be incorporated and situated well so as not to detract from what I am trying to make.  Selecting phrases was also difficult, because they had to work with or fit in with the meaning I wanted to convey.  I feel like I restricted myself too much with this type of poem construction.  If I were to do this project again, I feel like I would rather take a line from a poem and create a single poem centered around the excerpt, rather than cobble together a few verses from multiple poets into a single poem.
