1. Write your phone number in a column down the left-hand side of the paper.
2. Write a poem. Each line has the same number of words as the telephone number. A zero is a wild card, you pick the number of words.
Here's my example (slightly altered so you don't know my phone number)
Waves leave lines in the sand
At the farthest reach of the water.
Sparkles and fades
Of distant mountains
On the sandy canvas smoothed by the sea.
