In the evening of 18 July 2011, Amelia Fielden and I wrote four tan-renga sets together while travelling by ferry from Sidney, British Columbia to Anacortes, Washington. We had just attended the tenth annual Gabriola haiku weekend, and had carpooled together from Seattle. On the way home, I suggested that we try writing tan-renga together, and devised the sequence, which was to simultaneously write two tan-renga sets on a particular theme, each of us starting one of the two sets. After the first pair of sets, we tried another. The first two, “Through the Year,” progress through the four seasons. The second two, “Stages,” progress through the stages of human life. These four tan-renga sets were published in Red Lights 8:2, June 2012. Read them at “Four Tan-Renga Sets” on the Collaborations page.
