This hat is named for the “little mouths” on plant leaves that open up to allow for the exchange of carbon dioxide and oxygen necessary for photosynthesis and respiration (I learned something in high school biology!).

The orderly eyelet rows on this slouchy hat create structure and texture, and allow for some air flow to the wearer’s head, making this the perfect accessory for a summer evening.

Knit in the round from the brim to the crown, the hat incorporates decreases to preserve the fancy eyelet circles, even ending with a 6-eyelet flower. Make it green to stick with the plant theme, or choose your favorite solid or variegated yarn!

The pattern is a 4 page pdf file with color photos and detailed written instructions, suitable for beginners and experts alike.
