Here's another free pattern for you. It's a cute pumpkin-shaped hat with a rolled hem. It's very similar to some other pumpkin hat patterns I've seen on the internet, but I consider it sufficiently different to publish it here as a pattern. Feel free to use it, but please don't redistribute it without my permission.
Size: The hat should fit a head of about 39 cm circumference.
Yarn: I needed less than one ball (<50g) Gedifra For You, originally col. 1616 (silver gray), which I had dyed with Kool-Aid (1x mandarina tangerina + 1x orange). For the stem, I used leftovers of Rowan Lightweight DK, which had the perfect shade of green but was unfortunately a bit too thin (I should have used two strands of it).
Gauge: 24 sts (4 inches/10 cm) with smaller needles, 21 sts with larger needles
Needle size: Unfortunately, I can't remember which needles I used (d'oh!). I think it was either 3.0/3.5 mm or 3.5/4.0 mm.
Directions: Cast on 75 sts with smaller needles and join to round, place marker. Knit 1 inch (2.5 cm) in stockinette stitch (= knit every round). Next round: *knit 15, m1 (= make one)* [5 sts increased]. Next round: Change to larger needles and *k9, p1* all around. Keep knitting in pattern for about 4 inches (10 cm) with hem rolled / 5 inches (12.5 cm) with hem unrolled.
Next round: Start decreasing
*ssk, knit 5, k2tog, p1* all around, knit next 2 rounds in pattern
*ssk, knit 3, k2tog, p1* all around, knit next round in pattern
*ssk, knit 1, k2tog, p1* all around
Change to green yarn and knit one round of stockinette stitch.
Next round: Knit 4 sts, *work centered double decrease (= slip 2 sts together as if to knit, knit 1, pass the slipped stitches over the stitch just knit), knit 1* 8 times [16 sts]
Knit to marker and the next 3 rounds in stockinette stitch.
Next round: *k2, k2tog all around* [12 sts]
Next round: knit all sts
Next round: k1, k2tog all around [8 sts]
Next round: knit all sts
Next round: k2tog all around [4 sts]
Place the remaining four stitches on one needle (it has to be a double pointed needle) and knit an I-cord. The stem should be 2-3 inches long. Break yarn and thread it through all stitches twice, then thread it through a tapestry needle. Bend the stem to the side and pull the needle with the yarn to the inside of the stem and down, then weave the end in on the inside. Now weave the other ends in too and you’re done!
*Kürbis means 'pumpkin' in German and is pronounced ['kYrbIs]. The sound [Y] is a close, front and rounded vowel, similar to u in the french déjà vu. If you want to articulate it correctly, try to pronounce i (like in bit), but with rounded lips.
