Today's tool is brought to you by: PURPLE COWS and it is the : ROLL IT!
The Craft Geek Roll It can be used to add borders, accents and creative techniques to your projects with ink or chalk. The four pattern stamp balls are snowflakes, dots, hearts and stars and they can be easily changed for a variety of artistic techniques. Roll It can also be used without ink to add texture to clay, foam and foils.
It's price point is $14.95. I have only spotted it online as of this post but hopefully it will make it to a crafty store near you soon.
