Dust Bunnies love to hang out with you while you work on your computer and help you clean your screen with their noodly tentacle-y legs. They are very easy to make and make great gifts! I’ve included two patterns so you can make a bunny or an alien one.

In addition to sharing the pattern and instructions for making your own. she also sells these dust bunnies in her Etsy shop!
