Kanniks Korner directions have you sew everything, then cut the fall, which was done here.
On the right, the cut is made, the bearer tucked under, and the striped lining whipped over the cut edge. The welt gets folded, origami style, around an interfacing piece. More details are here. Super narrow fall on these babies.
GCV right down to the odd detail of both tails in back. Here it is before gathering for the knot. Anyone who has made cockades or put bows on bonnets will recognize this. Once the bow and band are gathered and knot applied, the band end is sewn down. Stock finished.
