Pattern Instructions
A. Granny Squares (Make 5)
Round 1:
- Make a magic ring.
- [Ch 3 (counts as dc), 2 dc] in ring, ch 1.
- [3 dc in ring, ch 1] repeat three more times (4 clusters total).
- Pull ring tight. Join with sl st to top of starting ch-3.
- Fasten off or continue to next round.

Round 2:
- Ch 2. In each ch-1 corner space: [3 dc, ch 1, 3 dc, ch 1] (work two clusters in each space separated by ch 1, for four corners).
- After the last cluster, join with sl st to top of beginning ch-2.

Round 3:
- Ch 2.
- In each corner ch-1 space: [3 dc, ch 1, 3 dc, ch 1] (two clusters in corner).
- In each side space between corners: [3 dc, ch 1] just once (single cluster).
- Continue to work corners/sides as established for a square.
- Join with sl st to top of ch-2.

Round 4: (Final Round)
- Repeat: In each corner ch-1 space: [3 dc, ch 1, 3 dc, ch 1]; in each side space: [3 dc, ch 1].
- Join to starting ch-2.
- Fasten off and weave in ends.

B. Join Granny Squares
- Lay out all 5 granny squares: 4 for sides, 1 for the top.
- With right sides together, join squares using slip stitch (sl st) seam—insert hook in BLO of one square and FLO of adjacent square, sl st to join.
- Seam all the way along sides, joining four sides to form a tube/crown and one on top for the cap.
- Continue joining all sides as needed, making sure all seams are neat and firm.
- Weave in all ends.

C. Brim (Worked Flat)
With contrasting color:
- Ch 26.
- Row 1: Sc in 2nd ch from hook and each ch across. (25 sc)
- Row 2: Ch 1, turn. Sc in first st (under both loops), sc BLO in next 23 sts, sc in both loops of last st. (25 sc)

- Repeat Row 2 for a total of 60 rows (or to fit snugly around bottom edge of hat when slightly stretched).Note: Both edge stitches of each row are worked under both loops for easier assembly, the rest are worked in BLO for ribbing.
- When desired length is reached, fold brim in half, short ends together.
- Seam ends using sc across to form a tube/circle.

D. Attach Brim to Hat
- Place wrong sides together: align brim’s seam with a seam of the hat.
- With hat right side out, single crochet through both layers all the way around:
- Insert hook through edge loops of both hat and brim, sc to join evenly.
- You can alternate: one sc in the valley, one at peak, matching the number of rows/stitches to the edge of the hat.
- Sl st to first sc to join, fasten off, and weave in ends.

E. Finishing
- Turn hat right side out.
- Fold brim upward to double the thickness over the ears.
- Attach decorative tag if desired.
- Your hat is now complete!

Conclusion
You have created a unique, customizable, and warm granny square hat with a thick, stretchy brim. This beginner-friendly project is perfect for using up scrap or variegated yarns and makes a fantastic gift or personal accessory.
Pattern Corrections & Tips
- If you prefer a different join, use single crochet seams or tapestry needle whipstitch.
- For larger/smaller hats, adjust size by making larger/smaller squares, or change the number of brim rows.
- Stretch the brim slightly as you crochet it on for a snug fit.
- Both ends of the ribbing (brim) should always be worked through both loops for stability and easy seaming.
- Sew granny squares securely at all joins to prevent holes.
