Your rhymed 14-line fly is open
From the notebooks of poet Winfield Townley Scott:
"A man may write a poem with his fly blatantly open — but the blatancy must not be in the poem."
And: "Oh, it appears too that there are those who maintain that the typewriter influences — or should influence — the length of the poetic line. God knows in what way or why."
