These are a cool way to organize your earphones /phone charger/ computer mouse cord, etc..., all while adding a little eye candy to your cord storage. This is also a great scrap busting project. I simply cut out circles of fabric (using a wide mouthed drinking glass as a template), then sewed two circles of fabric right sides together with a small loop of elastic embedded in the seam, leaving a small gap. I then turned the circle rightside out, ironed down the gap seam and then topstitched the circle in coordinating thread. Finally, it is just a matter of hand-sewing on a button across from the elastic loop and you are good to go!
I have been experimenting with making small individual sized tacos, but this can easily be adapted to some of those unwieldy cord spaces (behind the TV, computer desk, kitchen, etc...)
Have fun, and don't forget the guac!
