Ooooh! I want to try this. Look at these fun trees from Makin' Projiks. Great idea, lady! (All these photos are from Sarah on her blog.)
The basic idea: take those mini bottle brush trees you see everywhere at Christmas (You have 5 or 6 stashed away somewhere....right?) then bleach them. Then, take your tree and dye it in Halloween shades.
3. Now take those albino trees and dip them into some dye. Rit works, but I bet you could get by with plain old food coloring in a pinch. Or even Kool-Aid. Kool-Aid is so stainy it's practically toxic. I hate to see what my esophagus looks like after a glass of Kool-Aid.
These would be great for any holiday....I'm imagining pastel Easter trees, yes?
