22" x 4" cotton fabric
2" of 3/8" elastic
large safety pin
iron and ironing board
Cut your fabric. (I tapered it a bit on the end so it would fit under the head a little better.)
Fold material in half, wrong side out and iron flat.
Open up the material and sew 1/4" seam at the ends. Fold material back in half and sew (wrong side out) all the way down one side, back stitching on both ends. Make sure you don't sew the ends shut! (TIP- If you don't want to sew the ends shut you can use fray stop to prevent fraying.)
Put the safety pin on the end of one side. Push that down through the hole.
Sew the material flat again.
Get your elastic. Stick the elastic in one end and straight stitch in place, going over it several times to make sure it holds. Measure your head and sew the elastic in place. It should be snug, but not too tight. You may need to cut your material a bit shorter if your head is smaller or if you're making the headband for a child.
