I crocheted these chokers when I was a teenager, and still wear them today. That was a half century ago, BTW… Some have ties on the ends and others have snaps. The ties give more flexibility with regard to who can wear them. Pins at center front are interchangeable. One photo shows a crocheted flower as ornament and another a purchased silk rose. All have grosgrain ribbon backing.
I did not use any pattern. The design is my own, and I wrote down what I did somewhere. If I ever find my scribbles, I’ll share them here.
