Download the alien headband template, print, and cut out the pieces you need.
Begin to make the alien by gluing the eyes in the middle of the alien's head.
Use a marker a few shades darker than the colored cardstock you use to draw some spots on the top of the head. Also, color in the end of the alien's head projections.
Take a headband extender and tape it to the end of the headband base. Repeat for the other side.
