Found this pretty neat Washer&Ribbon DIY Necklace on Nestled and just had to share! All you need are 20 to 30 1 inch metal washers (depending on the length you want), and about 1 yard of 5/8" wide grosgrain ribbon.
How To Do The Do?
Thread your ribbon up through washer #1, leaving enough ribbon on the end to tie the necklace when it's finished.
Thread the ribbon down through the top of washer #2.
Thread the ribbon back down through washer #1.
Pull the ribbon tight, so washer #2 is laying flat on top of washer #1.
Thread the ribbon back up through washer #2.
Repeat steps 2 through 5 for each additional washer. Once you've threaded all your washers onto the ribbon, tie the two ends of the ribbon together and trim off the excess.
And... You're done!
