About This Harry Potter Hat Pattern

This pattern creates a Harry Potter themed hat using the waistcoat stitch and colorwork graphs to produce crisp characters and monograms. It includes two brim options (two-toned ribbed and slip-stitch) and complete decreasing rounds to finish the crown neatly. The pattern is sized for child through large adult and uses bobbins for clean color carries.

Follow the included charts for two character designs and an initial motif, and use the bobbin instructions for minimal bulk. Perfect for fans who want a polished colorwork hat with a faux fur pompom finish.

Why You'll Love This Harry Potter Hat Pattern

I absolutely love this pattern because it combines bold colorwork with an approachable construction that yields professional-looking results. The waistcoat stitch gives the hat a woven knit look that I find both beautiful and durable. I enjoy the flexibility of two brim options — you can choose a stretchy slip-stitch brim or the striped ribbed brim used in the cover photo. Working with bobbins to carry color makes the motifs crisp and satisfying to complete. Overall this design is a fun challenge that rewards you with a striking finished hat.

Switch Things Up

I love how easily this hat can be customized by changing colors to match any house or team — try alternating colors for a unique design.

Want a chunkier, warmer hat? Use bulky yarn and a larger hook to create a quick, squishy version with the same graph.

For a mini version suitable as a keychain, switch to fingering or sport yarn and a smaller hook and follow the same charts reduced by tension.

I often swap the faux fur pompom for a crocheted bobble in a contrasting color to keep the whole hat handmade.

If you prefer no visible color carries, try intarsia techniques or duplicate stitch after crocheting the base in a solid color.

I like to add a little lining with fleece for extra warmth and to hide bobbin tails on the inside for a polished finish.

Try embroidering small details instead of carrying yarn when you want minimal bulk on the wrong side of the hat.

I sometimes convert the two-toned ribbed brim into a folded brim by making it twice as long before seaming for extra warmth around the ears.

For kids, reduce the rounds before decreases to create a shorter crown and a snugger fit; always measure against the intended head size.

I enjoy mixing yarn textures — a slub or tweed accent paired with solid worsted gives the motif a modern look while keeping the graph readable.

Common Mistakes & How to Fix Them

✗ Pulling carried yarn too tight will distort the colorwork and reduce hat stretch; leave a small slack when carrying yarn and check the fit frequently. ✗ Tight decreases can make the crown pucker and change the size unexpectedly; keep decreases loose and match the gauge before starting decreases. ✗ Skipping the backwards join or stitch marker will create a visible seam or shift in pattern placement; use the backwards join or a marker to keep the rounds aligned. ✗ Not using bobbins or securing color tails can cause bulk and tangles on the wrong side; make bobbins as instructed and leave slack when pulling yarn across to prevent puckering. ✗ Failing to check your stitch count after switching hook sizes may break the graph alignment; count stitches after the brim and before starting the graph to reach the 66 stitches used.

— Stitch Guide :

Info :

Waistcoat stitch- (also known as center post stitch) The trick with this stitch is to insert your hook in the middle of the post, just under the inverted "v", pull up a loop, yarn over, and pull your hook through both loops.

Info :

Waistcoat stitch decrease- Insert your hook into the "v" of the first stitch, pull up a loop, insert your hook in the "v" of the second stitch, pull up a loop, yarn over and pull your hook through all three loops.

Info :

Backwards join- Remove hook and insert hook into the back of the beginning stitch. Turn work around backwards. Pull working loop through to the inside of the hat. Do not ch1. Instead, pull the yarn up a bit to loosen, making it easier to start the next stitch. Turn work around forwards.

— Abbreviations :

Infos :

ch = chain. st = stitch. sl st = slip stitch. sc = single crochet. blo = back loop only. bb = back bump. wcs = waistcoat stitch. wcsdec = waistcoat stitch decrease. FO = fasten off. ** = marks the repeats around. () = final stitch count.

— Size & Gauge :

Info :

Size: Fits most. Teen-adult size hat measurements: 8 1/2" long x 10" wide at widest point.

Info :

Use the following hook size for the hat size you are making with the body of the hat directions: Child ages 6-10 or head circumference of 16"-20 1/2", I/9 (5.5mm). Ages 11 & up or head circumference of 20"-22", J/10 (6mm). Adult large or head circumference of 23"-24", K/10.5 (6.5mm).

Info :

Gauge: 7 wcs x 8 rounds = 2" with 6mm hook. 8 wcs x 8 rounds = 2" with 5.5mm hook.

— Pattern Notes :

Info :

Please read through the entirety of this pattern before starting. The techniques you need to know are: the waistcoat stitch, color change, backwards join, carry yarn, and follow a graph. I have added videos of these techniques on my Facebook page, “Jennifer’s Stitched Up.” Access my page with the hyperlink below. I also have a Facebook Group that has many supportive crochet artists that offer help with questions you may have. Join my group, “Stitched Up Community,” for access to free patterns and share your finished projects with us. Use the following tag @jennifersstitchedup. Waistcoat stitch along with the graph. Use loose tension when making the WCS. This helps with ease of insertion into the "v" of the stitch.

— Bobbins :

Info :

How to use bobbins: Pick up bobbin when needed, adding that color. Drop after use. When needed again in the following round pick back up and pull across the stitches, working over the strand you just picked back up and pulled across. Note: when picking it up and pulling it back across the stitches to use for the next round, you will need to make sure that it is not pulled tight by leaving some slack to work over. This will prevent it from puckering. Continue working in this fashion with each color, as it is not stated after each set of directions.

Info :

Make bobbins for the back side of either design you make. You can work from the skein on the front portion of the design. Use approximately 20" pieces of your scarf colors. Place each stripe of the scarf color in the first stitch added using this tail working upwards to complete that stripe. Do this for front and back design. You will use your bobbins at each place and just crochet along with the graph for this pattern.

— Brim: Options include Ribbed & Slip Stitch :

Item Name (Two-toned ribbed brim) :

(This brim is used for the cover photo) Fits most. For all sizes use a 4.5mm hook for brim. With brim color and 4.5mm hook ch 9, R1: sc in 2nd ch from the hook and in each ch across, ch1, turn (8)

Round 2 :

sc, sc in BLO next 6, sc ending with a color change, with alternate color ch1, turn (8)

Round 3 :

sc, sc in BLO next 6, sc (8)

Round 4 :

sc, sc in BLO next 6, sc ending with a color change, with alternate color ch1, turn (8)

Round R5-60 :

Repeat rows 3 and 4

Info :

Align the brim and slst into both back loops only from each brim side to seam shut. Adjustments can be made here. Try the brim on to check fit. If you need to take out rows or add rows this will change the directions up a bit. The end goal is to have the graph stitch count needed before working the hat design.

Info :

Switch to hook size needed for hat. 5.5mm child, 6mm teen-adult, 6.5mm large adult.

Round R61 :

* Sc next 9, scinc* around the brim. (66) Backwards join.

Info :

Picture shows color changes at the top. Each color is used for 2 rows.

Item Name (Slip Stitch Brim) :

Fits most. For all sizes use a 4.5mm hook for brim. With brim color and 4.5mm hook ch 9, R1: slst in bb of 2nd ch from the hook and in each ch across, ch1, turn. (8)

Round R2 :

slst blo across, ch1, turn each row to desired length. (8) (13" for child, 14" for teen-adult, 15" for large adult.) I use 14 inches for myself. This style brim is very stretchy.

Round R3 :

Align the brim and slst into both back loops only from each brim side.

Info :

Switch to hook size needed for hat. 5.5mm child, 6mm teen-adult, 6.5mm large adult.

Round R4 :

Sc around the brim, attempting to get to 66sts before you start the graph. (I usually sc next 2, scinc.) Backwards join, ch1. (66) The end goal is to get the stitch count needed for the graph. You can count your rows and figure out how many increases you will need to add, then make them accordingly. If you did not get the amount of stitches needed, this design allows you to easily add increases to the next round to obtain the 66 stitches used.

— Child-Adult :

Info :

child I/9 (5.5mm). teen-adult J/10 (6mm). large adult K/10.5 (6.5mm)

— Body of Hat :

Info :

Continue with hook needed for hat size you are making. Make color changes along with the graph. Crochet the wcs, using loose tension throughout. Work continuously without joining. Use a stitch marker to keep your place.

Round R1-17 :

With all colors, follow along with the graph, using the bobbin directions. (66)

Info :

Start of decreasing rounds Friendly reminder, keep the decreases loose. It is easy to tighten tension while decreasing.

— Detailing :

Info :

Using the graph for placement of details: Split a piece of black worsted, (or you can even use sport weight). Using only 3 strands of the worsted and a yarn needle sew on the glasses. Do the same with the scar, in red. Then black or brown for the wand, on both front and back sides. With gold add a spark onto the wand tip on both front and back sides.

— Graph Notes :

Info :

Decrease rounds are highlighted in yellow. The stitch count of the decrease rounds are next to the highlights. Follow the graph from either left or right side. Rounds are numbered on the left and right of the graph. Stitches are numbered at the bottom of the graph.

Assembly Instructions

  • After completing the crown decreases, leave a long tail and cinch the opening closed, then sew the hole securely with the yarn tail and a yarn needle.
  • Attach the faux fur pompom to the top center of the hat by threading the pompom ties through the hat crown and knotting securely on the inside; weave in ends.
  • If you made a ribbed brim, align brim edges and slst into back loops only from each brim side to seam shut, then join the brim to the hat body and backwards join as instructed to avoid a visible seam.
  • Use bobbins to carry color across the wrong side and weave in all loose ends; trim and tidy bobbin tails to reduce bulk before final blocking.
  • Use a yarn needle and three-strand black worsted to sew on glasses, the scar, and wand details following the graph placement; check both front and back designs when adding details.

Important Notes

  • 💡Use stitch markers to keep track of your rounds, especially when working continuous rounds without joining to maintain pattern placement.
  • 💡Work with loose, even tension when making the waistcoat stitch to allow easy insertion of the hook into the "v" of each stitch.
  • 💡Do not pull carried yarn too tightly across the wrong side; leave slack to prevent puckering and loss of stretch.

This Harry Potter inspired hat pattern delivers bold colorwork and nostalgic charm in every stitch. Perfect for gifting to fans, it includes two brim styles and full color graphs for crisp characters and initials. Make a cozy, magical hat and top it with a fluffy pompom for a finished look. 🧶✨🧵
