ABOUT THIS PATTERN
This one-size-fits-most hat is a great gift for the science-lovers in your life! The hat is created from the band up. The band is crocheted using cables and the rest of the hat is crocheted using the half double crochet stitch. A drawstring is woven through the band of the hat to make it adjustable to any sized adult head! Finally, an optional red blood cell and pompom can be sewn to the top of the hat using a snap so you can change up your look.

This pattern contains 14 pages of detailed instructions, including photos.
