Crochet Monster Hat Tutorial

Monster crochet hat pattern FREE
Hey there! I’m Emily from The Boy Trifecta. I’m excited to be part of Andrea’s fantastic series, but I do have a confession. I don’t really do handmade costumes. Well, at least not sewn costumes – we did this cardboard box robot thing last year. See, I REALLY hate to spend a ton of time on something and then only have it worn for a few hours. So, today I’m sharing something that your little one can use all fall and winter long! 
This little crochet hat should fit toddlers and young children. It fits both my 1-year-old and 3-year-old monsters.   
Crochet is really easy and fun. If you don’t already know how, now is the time to learn! I learned through watching YouTube videos, but there is also a Crochet School series going on right now over here.
sl = slip stitch
dc = Double Crochet
sc = Single Crochet
hdc = Half Double Crochet
For the hat, use a worsted weight yarn, a size H hook, and join each round with a slip stitch around the beginning chain.Total stitch count per round is in the parentheses. Starting chain doesn’t count toward the final stitch count. Repeat the stitch pattern between the asterisks until the end of the round.
Chain 4, and join with a sl in the first chain.
Round 1: 10 dc into the loop you just formed (10 dc)
Round 2: Ch2, *2 dc in each dc* (20 dc)
Round 3: Ch 2, *1 dc in the first stitch, 2 dc in next*  (30 dc)
Round 4: Ch2, *1 dc in first 2 stitches, 2 dc in next* (40 dc)
Round 5: Ch2, *1 dc in first 3 stitches, 2 dc in next* (50 dc)
Round 6: Ch2, *1 dc in first 4 stitches, 2 dc in next* (60 dc)
Round 7-18: Ch 2, *1 dc in each dc* (60 dc)
Fasten off.
To make the smiley mouth on the front of the hat:
Count 20 stitches around from where you fastened off IN THE DIRECTION YOU CROCHET (this is different for lefties and righties) and attach yarn.
Row 1: Ch 2, dc in next 5 stitches, hdc in next 10 stiches, dc in next 5 stitches
Row 2: Ch2, turn work, dc in next 5 stitches, hdc in next 10 stitches, dc in next 5 stitches
Row 3: Repeat row 2. Fasten off. Weave in end, and flip mouth up toward the hat.
Using a small piece of felt, cut two triangles and place them like teeth between the hat body and the mouth. Stitch in place with a needle and thread.
Round 1: Make a magic loop, and do 10 sc in the magic loop. (10 sc)
Round 2: 2 sc in every stitch (20 sc)
Switch color
Round 3: *Sc in 2, 2 sc in next* (30 sc)
Round 4: *sc in 2, 2 sc in next* (40 sc)
Fasten off, and leave tail long enough for sewing onto hat.
Spikes (these are basically just shorter versions of these dino spikes):
Round 1: Make a magic loop/ring, and do 6 single crochets in the loop. Pull tight. (6 sc)
Round 2: Single crochet around (6 sc)
Round 3: 2 single crochet in first stitch, 1 sc in next stitch – repeat around (9 sc)
Round 4: Single crochet in each stitch (9 sc)
Round 5: 2 single crochet in first stitch, 1 sc in next stitch – repeat around (14 sc)
Round 6: Single crochet around (14 sc)
Round 7: Single crochet around (14 sc)
Fasten off, and leave a long enough tail to sew to the top of the hat. 
Sew all of your spikes and your eye onto the hat, and then send your little monster out to play (or rake the yard – whatever)!
Thanks for having me Andrea!

    This is so cute!
    To make it fit an adult, would it be better to simply add more rows (past the 18 stated above) or to add more chains in the first row (instead of 4 chains in a slip stitch, do more)? My friend is dying for one of these and I told her I would make her one. I just want to make sure it looks good! :)

    I don’t crochet and my daughter wants this Monster Hat for my grandson. Any chance someone may have a knitted version of this fantastic hat? I am unable to find any knitting patterns close to this.
    Any help will be greatly appreciated.
    Thank you!
