I make lashes for some regular drag clients - get basic fan strips, snip white craft feathers to size and glue them onto the base of the lashes with latex adhesive. If youre careful enough, they won't seperate when he gets a sweat going. If they need to be more rigid, give them a squirt with a non-flaking organic spray starch.
I make black duck down lashes for myself all the time, they look amazing.
