I originally wanted to bleach the blue fringe to make it ombre from white to blue, kind of the reverse of this one. However, apparently the fringe I bought would be impervious to nuclear attack, because even after an hour of sitting in undiluted bleach, it was still as blue as ever. So onto Plan Silver Sharpie!
Pliers of some sort
White or silver sharpie (or bleach, if your fringe is less hearty than mine)
What you do:
1) Cut a length of chain as long as you want your necklace (keeping in mind that the fringe will hang down a bit), and attach the necklace clasp to the chain.
It's a heart! Kinda.
3) Whip-stitch, sew, glue, or otherwise attach your fringe to the chain at the center.
