It originally was suppose to be a black zebra print but I couldn't find a black permanent marker so I had a red and it still turned out awesome!
First, You need plain color sun glasses [ones that you don't use anymore], preferably white because it's easier to draw on.
It's easier to start on the sides. Take your color marker and kind of outline a squiggly triangle.
Fill in the "squiggly triangle", so it should look something like the picture to the right.
Repeat this process all over the sunglasses, it might be hard in the front because the rims are small, so I just kind of added squiggly lines.
then you're finished! <3
