This was SO easy to make! and it cost me a whole .50 cents!!!
1/2 yard fabric netting (it was $1.99 a yard at joannes, then use the 50% coupon form their mailer)
fold your netting in half and sew up both sides.
fold down the open end a few inches and sew all the way around the top to create a tube to string the shoelace through.cut a hole in each end and sting the shoelace through, tie the ends together and pull top closed :)
