What you'll need:
yarn or ribbon
lightweight cardboard (like a cereal box)
First thing I had to do was measure two pieces of construction paper to make 21 inches. You'll have to glue them together to get the right length. I also added a bit of packaging tape to make sure it's secure. When they were dry I folded it in half horizontally and cut them- this makes TWO for around the head. On "raw side" Clip 1-inch slits around the top of the tube and bend them inward to create tabs, measure around your childs head and tape together.
"Make a tassel for the cap by winding yarn four times lengthwise around a ruler to create 12-inch loops. Cut a 24-inch piece of yarn and tie it through the top loops of the tassel to secure. Slip the loops off the ruler. Clip open the bottom loops. Glue the tassel to the center of the cap."
