This scarf is a clever way to use this lacey ribbon yarn.
The design isn’t crochet as such.
One places two strips along side one another, uses a crochet hook to place a bead on a loop and then pulls the next alternating loop thru.

It’s hard to see the beads in the pictures but they’re very pretty and add glamour.

This made up more quickly than I anticipated.

Added more beads along outer edges.
