hides the empty
As I do in my own composition (for better or worse), I've now settled the stanza length and pattern, and although this is free verse, I'm compelled to stick with it until the end. Then, ordinarily, I'd do an immediate redraft allowing changes to the form which has developed organically. In this case, I won't have the authority to revise like that, so it's all the more important to get it "right" the first time. I thank you all for your suggestions, especially Savvy Wit and Verse visitors, and Matt and Daisy for nose and catch, which both had special merits, but I've gone with Tabatha's coat because of my matchy-match compulsion. (Yes, it also drives my home decor and fashion choices, even though I'm aware that matchy-match is out.)
So we have a 6-line stanza with 11 words, times two is 22, leaving 8 words for some kind of concluding stanza? Or we could alternate 6 lines/4 lines. Hmmmmm....
