Crochet Harry Potter Baby Hat – Accio!!

Harry Potter Fans – Crochet Baby Hat

Nineteen years ago, while working as a elementary school librarian, I read the Harry Potter books for the first time and became an instant lifelong FAN!!!

Today, as I searched for a special type of baby crochet shower gift idea, “Harry Potter crochet” appeared in my google search list. PERFECT! I am going to crochet a Harry Potter baby hat for a 3-6 month old baby.

There are about as many measurement charts floating around on the internet as there are spiders in the forbidden forest, so here are a couple of PRO TIPS:

  • If you are following a pattern you’ve never used, crochet a 3” gauge swatch before you begin the project.
  • For every project, follow pattern instructions, count your stitches, and measure carefully from start to finish. This tip saves time and mistakes. Trust me, I know!
  • Those of you who are fortunate enough to have a baby in your life, take and use baby’s measurements as you go! If not, check out these approximate sizes:

Size: Preemie 4-5 lbs (Flat Circle Diameter: 3.18″; Length: 4″)

Size: Newborn (Flat Circle Diameter: 3.82″; Length: 5″)

Size: 0-3 Months (Flat Circle Diameter: 4.45″; Length: 6″)

Size: 3-6 Months (Diameter: 4.77″; Length: 7″)

Size: 6-9 Months (Diameter: 5.5″; Length: 7½”)

Size: 12 Months (Diameter: 6½”; Length: 8″)

Size: 24 Months-4T (Diameter: 6¾”; Length: 8½”)









Basic Crochet Baby Hat


#4 weight yarn

H hook


Measuring Tape


Notes: I used I Love this Yarn Red and Yellow. You can do your own stripe pattern or make the hat in one color. You are the artist–use your creativity. The pom pom was made with both colors.


Magic Ring

See “How to Make Magic Ring” instructions and pictures for right and left-handed crocheters here:

Holding yarn tail between thumb and pinkie finger, wrap yarn over first 2 fingers to make an “X”. Turn hand over to find 2 strands. Using hook take strand closest to fingertips and go under second strand. Hook second strand, twist hook and pull back under first strand, making a chain stitch. SC (or DC–follow your specific pattern instructions). When you’ve got your desired stitches, slip stitch into top of first chain and pull tight to gather stitches together.

ch – chain

st – stitch

sl st – slip stitch

Pattern Instructions:

Make magic ring, ch 2

Row 1: 12 dc, pull tight, sl st to top of ch 2, ch 2, turn

Row 2: dc in same ch 2 st, dc 2 sts in each st around (24), sl st to top of first st, ch 2

Pom Pom:

Step 1: Cut 12” length of yarn and set aside

Step 2: Using color(s) wrap around 3 fingers (about 75 times for 1 color/strand and 40 for 2 colors/strand)

Step 3: Using strand of yarn, tie tightly around wrapped yarn

Step 4: cut all loops

Step 5: trim (as desired)

With hook, pull 2 strands of yarn–to tie pompom in place–through to inside of hat and weave them in.

The glasses and lightning scar were made with black and silver yarn–both chains and sewn into shape.

 Ready Potter-head!

I am really pleased with the finished hat! It catches the eye and will probably start a few interesting conversations. Because most of the items I crochet end up being given away, and this time is no exception, I’m adding a package of flavored jelly beans to the gift bag, then I’m off to welcome a new little muggle into the world!

Happy crocheting!
