-Pick initial necklaces with a common element: same color metal or stones, ethnic influenced, biker, etc.
-Use different lengths (so they don’t tangle), with at least a couple inches between them; double them if they’re too long.
-Vary textures; alternate delicate and chunky.
-Mix your message: a Name Necklace on one chain, handcuffs or a skull charm on another; a peace symbol on a third.
If it’s still daunting, you can cave and buy one Custom Name Necklace with different elements that make it look layered without the fuss (or fun) of DIY.
