Pumpkin body: with orange yarn, magic ring, 6 sc. [6]. Round 2: increase every stitch. [12]. Round 3: (sc, increase) 6 times. [18]. Round 4: (2 sc, increase) 6 times. [24]. Round 5: (3 sc, increase) 6 times. [30]. Round 6: (4 sc, increase) 6 times. [36]. Place your marker here on round 6 as a reference for the groove step later.
Rounds 7 to 12: sc around with no shaping. [36]. Round 13: (4 sc, decrease) 6 times. [30]. Round 14: (3 sc, decrease) 6 times. [24]. Round 15: (2 sc, decrease) 6 times. [18]. Insert safety eyes between rounds 8 and 9, about 6 stitches apart. This is the last chance before the body closes. Snap the washers firmly from the inside.
Stuff the pumpkin generously. Round 16: (sc, decrease) 6 times. [12]. Round 17: decrease around. [6]. Fasten off and pull shut, leaving a 30 cm tail to use for the groove step.
Grooves: thread the long orange tail onto the yarn needle. Push the needle down through the centre top of the pumpkin, out through the bottom, back up to the top, and pull firmly. This creates one vertical indent. Repeat, spacing 6 indents evenly around the body. Secure the tail inside the pumpkin.
Hat: with black yarn, make 2 flat circles. Circle 1 (brim): magic ring, 6 sc, increase every stitch to 12, (sc, increase) 6 times to 18, sc around to 18. Circle 2 (cone): magic ring, 6 sc, increase every stitch to 12, (sc, increase) 6 times to 18, (2 sc, increase) 6 times to 24, sc around to 24, then decrease 6 times in the next round (18), and again (12), and again (6), then pull shut. Sew the cone to the centre of the brim circle.
Stem: with brown yarn, chain 6, sc in the 2nd chain from hook and across (5 sc). Fasten off. Roll the strip between your fingers to form a small nub and sew it to the top centre of the pumpkin.
Vine: with green yarn, chain 20, slip stitch across to curl it, then fasten off. Sew the vine alongside the stem. Add a small flat leaf by chaining 5, turning, and slip-stitching back for a pointed oval shape.
Embroider a curved smile with black yarn using 4 straight stitches. Add two small French knots or felt circles in pink for the blush. Sew the hat to the top of the pumpkin at a slight angle.
