This is one of my favorite upcycle projects. It's easy, fun, and au naturale. It's a much better way to color your garments than harsh chemical dyes.
You'll have a really fun new clothing item and no one will believe them when you say it's all thanks to a fruit (I know right, so weird that avocados are a fruit)!
Start by collecting 4-6 avocado pits. I usually collect them slowly (saving the pits whenever I eat an avocado) and keep the in the freezer after washing them until I have enough for this project.
