Cut the foam or felt in a bib shape.
If you prefer, you can make a paper template for trying it before on your neck and then use it on the foam to cut a precise shape.
Cut CD’s creating a composition with identical shapes in pairs or you can keep all into small pieces with random order.
Start pasting from the center out. Now create a composition on both sides with equal pieces.
Finally, Put a ring at each corner and attach the chain. Done! An original recycled necklace.
