In this week’s installment of our Craft Capsules series [3], poet Trevor Ketner writes about setting specific parameters and inventing methods to guide their writing. For their first book, [WHITE] (University of Georgia Press, 2021), Ketner based a series of poems on the major arcana cards of the tarot: “Because the major arcana comprises twenty-two cards, I wrote twenty-two poems of twenty-two lines each,” says Ketner. Inspired by Ketner’s use of invented forms, choose a number significant to you and write a poem limited to that number of lines. Will having a set structure surprise you with the freedom to push your language?
