I had occasion to facilitate a small poetry enclave this fall, and for our final assignment we agreed to try our hand at a pantun or pantoum, originally a Malaysian form that in the west has settled down into four-line stanzas, the lines being of any consistent(ish) length; the 2nd and 4th lines of each stanza become the 1st and 3rd lines of the next stanza: repetition makes it sound like an incantation, as in a villanelle. The repeated lines may have different punctuation, of course, and you can swap around parts of speech, use enjambment to change your meaning, etc.
My own little exercise won’t win any prizes, but:
The St Lawrence used to freeze.
Without offense my forebears crossed
And didn’t get shot by a vigilante
Or have to pretend they were lost.
Today my family would row across
But now your tolerance is spent
And shooters pretend they got lost.
Courtesy’s turned to resentment.
Though your tolerance is spent
They come, facing your guns and chaos:
Courtesy’s turned to resentment
And the border patrol knows who’s boss.
