Starting a new year often means an attempt at challenging resolutions or constraints, but in poetry, constraint can seem natural and even fun. For example, in Oulipo [3], formulas and frameworks (some more complicated than others) are applied to the lines and words of a poem. Try this exercise in constraint: Write a poem in which all of the words contain a vowel of your choice. For inspiration, read “Ballad in A” [4] by Cathy Park Hong.
