Each line contains a particular number of words or syllables. The numbers can be anything: a special date, like a birthday, gps coordinates, your library card number... Whatever floats your poetic boat.
We used our own numbers, so our two poems will not match. Mikro's is word count oriented; mine is done by syllables.
Mikro:
I don't want to
Write
A poem with a specific number of words.
Chele:
September brings cool days and blue skies,
Autumn,
Colors popping.
And another:
I am riding on a south-bound train,
Eyelids drooping.
No wished for cup
Of steaming hot coffee
Appears.
Sigh.
Guess I will have to write a poem
To wake myself
...
