This crochet frankenstein pumpkin pattern turns a simple pumpkin into the iconic green-faced monster — complete with the classic flat-top hairline (created by changing colors mid-pumpkin) and two side bolts. It’s part of my Lil Monsters Pumpkin Patch, a free series of 8 costumed pumpkin patterns. 🧌

The signature look of this Frankenstein comes from a clever two-color pumpkin base — the first 16 rows are worked in spring green, and the remaining rows in black. When the pumpkin is seamed and stuffed, this creates the iconic black “hairline” across the top of the green face. Add two simple black bolts to the sides, embroider a face, and you’ve got Halloween’s most recognizable monster.

This blog post includes the crochet version of the pattern. The knit version is available as a bonus in the Lil Monsters Pumpkin Patch Bundle on Etsy.

Crochet frankenstein pumpkin pattern — written instructions

Pumpkin base modification (two-color)

Follow the simple pumpkin base pattern with these color changes:

  • Begin with Spring Green and work the first 16 rows
  • Switch to Black for the remaining rows of the pumpkin base

When the pumpkin is seamed and stuffed, the green portion forms the face and the black portion forms the iconic flat-top hairline across the top.

Custom rounded stump

The Frankenstein uses a custom rounded stump (similar to the Kitty Cat) for a polished, finished look on top of his head.

With Coffee, ch 4. Join with sl st in the first ch to form a loop.

Round 1: 6 sc within the loop. (6 sts)
Round 2: Sc in back loops only of each st around (this creates a small ridge). (6 sts)
Rounds 3–7: Sc in each st around. (6 sts per round)

Fasten off, leaving a long tail. Lightly stuff with polyfil and attach to the top center of the pumpkin.

Bolts (make 2)

The bolts are small black tubes that attach to either side of the pumpkin head.

With Black, ch 4. Join with sl st in the first ch to form a loop.

Round 1: 6 sc within the loop. (6 sts)
Round 2: Sc in back loops only around (creating a small ridge). (6 sts)
Round 3: Sc in each st around. (6 sts)
Round 4: Sc2tog in back loops only around. (3 sts)
Round 5: Sc in each st around. (3 sts)

Fasten off, leaving a long tail. Repeat for the second bolt.

Assembly

  1. Attach the rounded stump to the top center of the pumpkin (in the black “hair” zone) using the long tail and tapestry needle.
  2. Position the bolts on either side of the pumpkin’s “neck” — at about the level where the green face meets the black hairline. The bolts should poke out horizontally from the sides.
  3. Sew each bolt in place with the long tail and tapestry needle, anchoring firmly so they stay positioned.
  4. Embroider the face. Using black yarn and a tapestry needle, embroider the Frankenstein’s face — typically two simple eyes, a flat horizontal mouth (or a slightly downturned grumpy mouth), and a small scar or stitch detail across the forehead if you want extra character.
  5. Weave in any remaining ends on the inside of the pumpkin to keep the front clean.
