DIY knot bow headband! by DIY knot bow headband!DIY cute knot bow headbands. You will need jersey fabric (upcycled old t shirt), a sewing machine, thread, paper, straight pins and scissors. Cut about 22"x5" in fabric (for a 12 month old), after it is cut fold it in half, cut the ends of the fabric to have round edges, pin the fabric and sew it together, leave a little section open to turn the fabric right side out then hand stich the space shut. finally tie the ends in a square knot! here is a link to the tutorial http://morgans2day.blogspot.com/2013/06/diy-top-knot-jersey-knit-headband.html?m=1
