but it leads to some weak poetry (IMO) because of the line length restriction.
Still, in an attempt to follow said form (just for kicks):
and horse-hair strings
through her glass
his hands tremble
across the neck
Again, a lot of these line assignments seem arbitrary. I wonder what the other people in the class came up with, or if this was based on an actual poem?
I know a good writing exercise is to take a favorite poem--usually something short and pithy--and, based on the phrasing, figues of speech, etc., write your own poem. It's a great way to learn rhythm, and how to apply language to a line, etc. I think I'm curious as to what this assignment was based on.
