Write a poem of about thirty lines that consists of a single sentence. Experiment with clauses and phrases and parallel structure. Try to keep the sentence moving forward, enjambing it across lines in different ways, while making sure it is grammatically correct. This type of exercise will help you develop flexibility as a writer, teaching you new ways to phrase things and new ways to play with the syntax of a line.
As always feel free to post your work in Poetic Scriptures if you'd like some feedback, with the required two links of course.
Have fun and be creative.
