I wanted to try my hand at making a coif, so I looked on Utube and found this video … . I’ve completed the crown and the initial 54 rings around the crown. I understand that it’s necessary to expand the crown until it fits your head. I also understand you expand by adding a ring between two existing rings. My question is, do I add these additional rings all the way around or just occasionally on each row around the crown until it fits my head?
