Sometimes you just need a new tool. Especially if you're already at the hardware store buying paint for the kitchen ceiling.
And if the price is right, and it is a nice color combination, why not? It is fun to buy something that's intended for one use and then go and use it in a completely different way. Oooh, call me a rebel! This is actually for doing tile work, as you can see by the picture, but I'm going to use it for painting and mono-printing and maybe screen-printing if I get my act together.
Squeegee, isn't that fun to say?
