A rope bracelet - reminds me of making friendship bracelets back in the day. My right second toe used to go numb because I'd hook the end of the bracelet over it, and then knot embroidery floss for HOURS.
Super cute idea for displaying kid art! :) I did this in our great room the kids love to change their work and when they make something they decide if they want to put it up on the wall. For when I have grandchildren. Should just start a new board.
