You take a line, a stanza or an entire poem by another poet and use each word in the beginning of each line of your own poem. Additionally, you give credit to the original poet and their poem.
I love this line from Anna Bartlett Warner's poem:
Jesus loves me this I know for the Bible tells me so.
Jesus has always been in my heart
Love from Jesus won't depart
Me is myself and who I am
This is the me that Jesus saved
I wouldn't be here without faith
Knowing Jesus makes me feel safe
For my security rests upon Him
The life around me isn't my first love
Bible verses help me focus on heaven above
Tell me, in what is your spiritual trust placed?
Me, I am always safe, secure, and loved.
So I know, I am the winner of life's race.
