I saw this at another poetry site (i am fickle).
It is called a 'bout-rimes.' I first heard of this when reading about it this morning. It is a poem created by one person's making up a list of rhymed words and giving it to another person, who in turn writes the lines that end in those words, in that same order.
Here is the 'challenge' I found. It is in English or Shakespearean sonnet form.
If anyone is really interested and needs a little more 'sonnet' info, just ask.
The challenge is to create a sonnet using the end-rhymes in this order:
June
stress
moon
obsess
snake
moot
cake
beaut
Garbo
play
hobo
day
rhinestone
cologne
I played around with this for a couple of hours this morning and was able to come up with something. So it is do-able

Laurie
