These little bows are made of 100% wool felt. They measure approximately 1.5" x 2.5" and are attached to a nylon headband.
Nylon headbands are soft and don't need to be measured. Nylon headbands stretch to fit from newborn to adult. They do not rebound like elastic headbands. Allow the headband to slowly stretch as your little ones head grows, but don't over stretch.
