Swap Quatrain:
Each stanza in the poem must be a quatrain (four lines) where the first line is reversed in the fourth line. In addition, line 2 must rhyme with line 1, and line 3 must rhyme with line 4 and so on, BUT not repeat the same rhyming pattern on subsequent stanzas.
Rhyming patterns: AABB, CCDD, or ABAB, CDCD and so on.
