Working in 3s:

When organizing poetry into a series or larger manuscript, I often write in tripartites: maybe 3 short lyric poems or 3 sections of a longer poem.
Thinking in 3s also helps to structure a necklace series providing parameters, limitations & boundaries, i.e. taming creative chaos! 3 Jade Fish (below) are available @ Etsy | ZygosDesign.
