Pumpkin Head is part of the Spook-tober collection.

“Pumpkin” cables wrap the circumference of the hat. The sample shows a very slightly slouched hat, just a bit longer than a beanie. To create a longer, slouchier hat you may consider working the pumpkin section (rnds 19-38) another time and using size 8 needles after the bottom instead of the 7s the pattern calls for. If you do this you will require slightly more than a single skein.
