I cut off some bristles from a powder brush, laid down a thin line of e/l glue on a plastic surface and let it get tacky. Then I placed the hairs on top of the glue and pressed down with a small metal spatula. After it dried, I added more glue, placed a thin strip of fabric over the glue and let dry again. I carefully peeled up the "lashes," trimmed them and curled them with a small curling iron.
I made some from peacock feathers that I'll post another time.
