We've got spirit-Hair!

I love crazy hair and sports days! I use my silhouette or cricut (I have both) to create the stencils and use hair gel to hold them in place while I spray the colors. It's a little bit of work but oh so worth it to have the coolest hair around!
I love the pink and purple version! It pops right out. The possibilities are endless
If we have crazy hair day again maybe I will put together a tutorial on how I make this happen!
