The trick to these pumpkins is all in the face. I cut out little triangles for the eyes and a toothy grin from the black felt (and hey, don't worry if they’re not perfect triangles—mine were more like lopsided squares, and they still looked great). Stick those on with your hot glue gun, and suddenly, your little yarn ball has this adorable jack-o'-lantern vibe. It’s like they just came to life!
