Blackout poetry~ What an impressive and creative idea. I never thought of doing something like this. Making these is like putting together a puzzle. Plus, it's a lovely way to stitch together a little fantasy story and get yourself in the right mindset to create some cool art.
National Poetry Month idea? Have a container full of words (nouns, verbs, adjectives, etc.) and also residents to mix and match them. They could be hung by pins or Velcro. Perhaps once a week residents could vote for their favorite poem?
