Peel the backing off of the sticky felt and place each piece of colored felt on top. Be sure to line up the bottom edge and fit colors as close together as possible. Turn your crown over and trim the colored felt along the edges of the crown.

Using an X-acto knife (or scissors) cut a small slit on each side of the crown.
Cut two pieces of ribbon about 18" each. You can adjust length of ribbon depending on the child's head size, but leave plenty of extra to tie in a bow. Thread ribbon through the slits and tie in a knot.
