DIY Body Necklace

Found this a-maz-ing body necklace made out of rope on Brook and Lyn.You can buy the design on her website (which is also filled with many other amazing treasures), but I might give it a go to DIY? Although, I am sure I could never DIY the amazingness that is the galactical crystal in the middle, so maybe I need to start saving my pennies...?
