I have always wanted to try painting feathers and it's surprisingly simple (although these are pretty amateur)! This lovely DIY was inspired by Free People. I recommend using white feathers because they'll take to the paint easier. Start with one color and paint the whole feather, or use a striped pattern (red, white blue). Then let the feathers dry, it only takes a few minutes, and add some detailed patterns to them. Have fun with it, don't think too much!
Then play around with your beautiful, colorful feathers.
I leather wrapped the end of one to make a key chain for my boring old keys..
