I’ve made some new collars, two using navy velvet and one crocheted.
The velvet collars are lined with navy cotton drill.
There are images of the collars I’d made before here.

This one is embroidered with cotton yarn and beads.
Fastens with cotton grosgrain ribbons in cream colour.

This one has very delicate silk crocheted trimmings.
Fastens with cotton and acetate grosgrain ribbons in grey.

This cotton yarn is shiny like silk but it’s firm and doesn’t fluff, very good.
