I made this project while I was in Omaha but totally forgot to post it. This is an awesome technique you can use to make any shape of headband but a heart one would be perfect for Valentine's Day!
Make a paper template for your heart and choose a thick fabric like leather or vinyl.
Sew the two pieces together around the edges with your sewing machine.
Cut out two hearts from the thick fabric.
Get a small pot and mix together a lot of glitter with mod podge.
Use a foam brush to paint the fabric heart with a layer of glittery mod podge and leave to dry.
Paint with several layers until it's super glittery.
Glue on to a headband and you're done!
