Reusing Crochet Swatches as Erasers

As many of you know, during the day I work as a teacher. Though I studied psychology as my Bachelor's and elementary education as my Master's, I am currently teaching humanities courses to middle and high school students, with a few younger kids in there whenever the need arises. The one-on-one style school that I work for is dedicated to providing a distraction-free environment where kids who are having a hard time in public school can focus and achieve success.

Though we understand the need for a crisp, clean teaching environment, my fellow instructors and I have found a few ways to make it more personal without distracting students. My contribution to the workplace was...can you guess? Crochet! I don't know about you, but I have an entire drawer of swatches just hanging around waiting to be utilized. Thus, I put them to work as whiteboard erasers!

Now there is a spot of crochet color in each station and my swatches have found a new life. Win-win! How do you like to reuse your swatches?
