You'll need some nice ribbon, some velvet ribbon, and a bit of elastic. Measure the head over the ears in a loop to the nape of the neck. For a small child this would be about 21". The velvet ribbon should be a discrete color that will not show when it lies against the hair. The nice ribbon will be visible over the head.
Cut three inches of elastic - I'm using soft elastic lace for comfort.
Take the head measurement and subtract three inches, use this measurement for the velvet ribbon and the nice ribbon that will show. I chose 5/8" to give the headband enough width to actually work with heavy hair.
Place the ribbons right sides together and the elastic sandwiched between. Stitch the end with a seam allowance of 1/4" to 3/8" (give or take).
Stitch the other side the same way.
Now, flip the headband to set the ribbons right-side out and stitch the open edges of the ribbon with a straight stitch.
Wear the headband behind the ears with the velvet against the head, the elastic part will be at the nape of the neck, under the back hair.
Enjoy!
