These lightweight chandeliers are created by tying together hand-blown glass balls with cables and cotton twine. Originally designed by Jean Pelle for ReadyMade Magazine, it's a beautiful design you can make yourself or purchase online.
Originally showcased in the Feb/March 2009 Issue of ReadyMade Magazine (PDF of article available here), the chandelier can be made from off-the-shelf parts for $75. Using hand blown glass spheres from CB2, the chandelier can be assembled in any size or dimension.
If you'd rather purchase a chandelier than make one, JeanPelle has four sizes available sale on Etsy.
