Today I restyled an old vintage necklace I had into a head-chain! It's really easy and you can use only the supplies in your home, you don't need to have any special equipment (I used nail clippers and scissors). If you've ever repaired, replaced or tightened a link on a necklace you're more than capable to handle this project.
I used the clippers to wedge open the links and the scissors to clamp them back together. You should create a "T" shape and keep the center chain slightly shorter then connect all 3 open links on the bottom.
That's all there is to it! I kept all the links in my necklace so it would be extra long, but you can also remove links to make it shorter or smaller on your head!
