10 Pretty Pink Vintage Flower Buttons / Beads- 8mm tall, 12mm wide

They are plastic, measure 1.2cm wide and stand 8mm tall. 

Probably from the 1960s - found them in an old button warehouse clearance.

They have a hole in the centre so would need to be held onto the material with a knot in the centre of the flower.

Or they could, of course, be used as beads.
