Materials Needed: Gathering Your Supplies

Before you begin, it's essential to gather all your materials. This project uses simple, readily available supplies, making it an accessible knit for any crafter.

Yarn

• Weight: Worsted weight cotton or cotton blend (e.g., Lion Brand 24/7 Cotton).
• Colors: You will need two colors:
  • Main Color (MC): Soft cream (approx. 100g).
  • Contrast Color (CC): Dusty rose or sage green (approx. 50g).

Needles & Notions

• Knitting Needles: US Size 6 (4.0 mm) circular needle (16-inch length) AND double-pointed needles (DPNs) in the same size for crown shaping.
• Tapestry Needle: For weaving in ends and finishing.
• Stitch Markers: At least one, preferably a few.
• Small Button: A wooden or plastic button for the chin strap.

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch (knit on RS, purl on WS). It is crucial to check your gauge before starting. If you have more stitches per inch, try a larger needle; if you have fewer, try a smaller needle. Getting the correct gauge ensures the hat fits properly.

Step-by-Step Instructions: Knitting the Derby Dandy

This pattern is worked from the brim up. The instructions are for the newborn size (0-3 months), with larger sizes (3-6 months and 6-12 months) in parentheses. Let's get started!

Abbreviations

• K: Knit
• P: Purl
• K2tog: Knit two stitches together (right-leaning decrease)
• SSK: Slip, slip, knit (left-leaning decrease)
• YO: Yarn over (creates a hole/decorative increase)
• PM: Place marker
• SM: Slip marker
• RS: Right side
• WS: Wrong side

Part 1: The Brim (Worked Flat, Then Joined)

We begin by creating the decorative picot edge of the brim, which is worked back and forth in rows before joining in the round.

1. Cast On: With your Main Color (MC) yarn, cast on 84 (96, 108) stitches loosely. A long-tail cast-on works well here.
2. Row 1 (WS): Purl all stitches.
3. Row 2 (RS): K1, *YO, K2tog; repeat from * to the last stitch, K1. (This creates the picot edge that will form a decorative rolled brim.)
4. Row 3 (WS): Purl all stitches.
5. Row 4 (RS): Knit all stitches.
6. Row 5 (WS): Purl all stitches.
7. Row 6 (RS): Knit all stitches.
8. Row 7 (WS): Purl all stitches.

Join in the Round: Place a stitch marker at the beginning of the round. Critical: Ensure your stitches are not twisted on the needle. Now, work in stockinette stitch (knit every round) for 2 (2.5, 3) inches from the cast-on edge. This section forms the inside of the brim that will be folded up later.

Part 2: Crown Shaping (Decreases)

Now we will shape the top of the hat by decreasing stitches. All even-numbered rounds are plain knit rounds.

1. Round 1: *K10 (12, 14), K2tog; repeat from * to end of round. (77, 88, 99 stitches remain)
2. Round 2: Knit all stitches.
3. Round 3: *K9 (11, 13), K2tog; repeat from * to end. (70, 80, 90 stitches)
4. Round 4: Knit all stitches.
5. Round 5: *K8 (10, 12), K2tog; repeat from * to end. (63, 72, 81 stitches)
6. Round 6: Knit all stitches.
7. Round 7: *K7 (9, 11), K2tog; repeat from * to end. (56, 64, 72 stitches)
8. Round 8: Knit all stitches.
9. Round 9: *K6 (8, 10), K2tog; repeat from * to end. (49, 56, 63 stitches)
10. Round 10: Knit all stitches.
11. Round 11: *K5 (7, 9), K2tog; repeat from * to end. (42, 48, 54 stitches)
12. Round 12: Knit all stitches.
13. Round 13: *K4 (6, 8), K2tog; repeat from * to end. (35, 40, 45 stitches)
14. Round 14: Knit all stitches.
15. Round 15: *K3 (5, 7), K2tog; repeat from * to end. (28, 32, 36 stitches)
16. Round 16: Knit all stitches.
17. Round 17: *K2 (4, 6), K2tog; repeat from * to end. (21, 24, 27 stitches)
18. Round 18: Knit all stitches.
19. Round 19: *K1 (3, 5), K2tog; repeat from * to end. (14, 16, 18 stitches)
20. Round 20: Knit all stitches.
21. Round 21: *K0 (2, 4), K2tog; repeat from * to end. (7, 8, 9 stitches)

For larger sizes: If you are making the 3-6 or 6-12 month size and have more than 7-9 stitches remaining, continue decreasing in this pattern (K1, K2tog; then K2tog) until you have 7-9 stitches left.

Finishing the Crown: Cut your yarn, leaving a long tail (at least 8 inches). Thread the tail onto a tapestry needle and pass it through the remaining stitches on your knitting needle. Slide the stitches off the needle, pull the yarn tight to close the hole, and secure it with a knot. Weave in the end on the inside of the hat.

Part 3: The Lace Brim Edging (Optional but Charming)

This step adds a beautiful, delicate lace detail to the edge of the brim. It's a lovely touch that elevates the design.

1. With the Right Side (RS) facing you, pick up and knit one stitch for every cast-on stitch along the bottom edge of the brim using your MC yarn. Join in the round.
2. Round 1: Knit all stitches.
3. Round 2: *YO, K2tog; repeat from * to end of round.
4. Round 3: Knit all stitches.
5. Bind Off: Bind off all stitches loosely.

To finish the brim, fold it up over the hat body. Use your tapestry needle and a piece of MC yarn to tack the folded brim down at a few intervals with small, invisible stitches.

Part 4: The Buttoned Chin Strap (For a Secure Fit)

This playful and practical strap ensures the hat stays on, even on breezy days.

1. Create the I-Cord: With your Contrast Color (CC) yarn, cast on 4 stitches onto a double-pointed needle.
2. Work the I-Cord: *Knit 4 stitches. Do not turn your work. Slide the stitches back to the other end of the needle. Repeat from * until the cord measures 6 (7, 8) inches.
3. Bind Off: Bind off all stitches. Weave in the ends.

Attach the Strap: Sew one end of the I-cord securely to the inside of the hat at the brim edge on one side. Sew a small button onto the other end of the strap.

Create the Fastening Loop: On the opposite side of the hat, create a small loop to fasten the button. You can do this by crocheting a small chain of stitches (about 1 inch long) or by sewing a small loop of yarn. Make sure the loop is just big enough for your button to fit through snugly.

Part 5: Finishing Touches

1. Weave in Ends: Using your tapestry needle, carefully weave in all remaining loose ends on the inside of the hat.
2. Blocking: Gently hand-wash the hat and lay it flat to dry, shaping it as needed. This will help even out the stitches and give the hat a professional finish.
3. Styling: The brim can be worn up or down. For an extra touch of charm, you can add a small fabric flower or a knitted bow at the base of the crown.

And there you have it—a beautiful, heirloom-quality Derby Dandy Baby Sunhat that's ready to be worn and adored. This pattern is a joy to knit and makes a thoughtful, handmade gift for any new arrival. Happy knitting!
