From the 2015 Poetry Marathon
Write a sestina! A sestina is a poem with six stanzas of six lines and a final triplet, all stanzas having the same six words at the line-ends in six different sequences that follow a fixed pattern, and with all six words appearing in the closing three-line envoi.
Does that sound intimidating and time consuming? It only is if you do it from scratch, however there is a website that helps with the creation of sestinas: http://dilute.net/sestinas/
All you have to do is come up with 6 words and they will figure out the order of everything, then you can add the rest of the text yourself. A sestina can really get you writing about something you would normally not. They are great in that way.
