DIY Rattan Ball Patio Light Strand! Cost is $1 plus tax. Dollar Tree, and other dollar outlets, sell these grapevine deco balls by the bag. Take one of your strings of white Christmas lights, pop the rattan balls over each bulb, hang it up and plug it in! These deco string lights cost a lot when bought in retail stores. You can make your own and pocket the bucks for other DIY fun projects! Pssst! Use up some of the spray paint you have, or use colored lights, and change these up!
