From an original model Bergere de France, the edges of the top is a plait half knitting half plaited. It requires to knit 3 bandes that you plait. The bandes are knitted with 3st knit, 3st purl, 3st knit so they don’t roll when you plait them. It does add a luxurious touch to the top, “tres couture”. The difficulty is sewing and closing the bands together into a cercle. Any suggestions here will be good.
