Materials Needed

To create your own Aurora Borealis Slouch Hat, gather the following materials. Gauge is critical for fit, so take the time to check it before you begin.

• Yarn: Worsted weight (#4) yarn in 4 colors (approximately 280 yards total):
  • Color A (Deep Teal): 80 yards
  • Color B (Moss Green): 60 yards
  • Color C (Soft Gold): 60 yards
  • Color D (Dusty Rose): 80 yards
  Sample uses Lion Brand Wool-Ease in 'Fisherman', 'Forest Green Heather', 'Gold', and 'Rose Heather'.
• Hook: US Size J/10 (6.0 mm) crochet hook, or size needed to obtain gauge
• Other: Yarn needle for weaving in ends, scissors, tape measure

Gauge: 14 linked half double crochet stitches x 10 rows = 4 inches (10 cm) in pattern. Gauge is critical for fit.

Step-by-Step Instructions

Understanding the Linked Half Double Crochet (LHDC)

This pattern uses a special stitch called the linked half double crochet (LHDC). It creates a beautiful, braided texture that looks like tiny chains. Here’s how to make it:

1. Insert hook into the horizontal bar just below the top loop of the previous stitch (the 'V' shape).
2. Yarn over and pull up a loop (2 loops on hook).
3. Insert hook into the next stitch (the one you're working into).
4. Yarn over and pull up a loop (3 loops on hook).
5. Yarn over and pull through all 3 loops on hook. One LHDC complete.

Brim

The brim is worked flat in rows, then joined to form a ring. This creates a stretchy, ribbed band that fits snugly.

1. With Color A, chain 10.
2. Row 1: HDC in 2nd chain from hook and in each chain across. (9 HDC)
3. Row 2: Chain 1, turn. HDC in the back loop only of each stitch across. (9 HDC)
4. Repeat Row 2 until the brim measures approximately 20 inches (51 cm) unstretched, or desired head circumference. Do not fasten off.

Join Brim

1. Fold the brim in half, matching the short ends.
2. Slip stitch the ends together to form a ring. Be careful not to twist the brim.
3. Turn the brim right side out. The ribbing should now be a continuous loop.

Hat Body

The hat body is worked in joined rounds from the brim upward. You'll change colors every few rounds to create the aurora effect.

1. Round 1 (Color A): Chain 2 (does not count as stitch). Work 1 LHDC into each row-end of the brim. Join with a slip stitch to the first LHDC. (Approximately 60 LHDC, adjust to be a multiple of 4 for the decreases to work evenly.)
2. Round 2 (Color A): Chain 2. Work 1 LHDC in each stitch around. Join with a slip stitch to the first LHDC.
3. Round 3 (Color A): Repeat Round 2.
4. Round 4 (Color B): Join Color B with a slip stitch. Chain 2. Work 1 LHDC in each stitch around. Join.
5. Round 5 (Color B): Repeat Round 4.
6. Round 6 (Color B): Repeat Round 4.
7. Round 7 (Color C): Join Color C. Chain 2. Work 1 LHDC in each stitch around. Join.
8. Round 8 (Color C): Repeat Round 7.
9. Round 9 (Color C): Repeat Round 7.
10. Round 10 (Color D): Join Color D. Chain 2. Work 1 LHDC in each stitch around. Join.
11. Round 11 (Color D): Repeat Round 10.
12. Round 12 (Color D): Repeat Round 10.

Decrease for Crown

Now you'll shape the top of the hat by working decreases. The LHDC2tog (linked half double crochet two together) is worked as follows: work a LHDC but skip the last step of pulling through all 3 loops, leaving 2 loops on hook; work another LHDC in the next stitch, but again skip the last step, leaving 4 loops on hook; yarn over and pull through all 4 loops.

1. Round 13 (Color D): Chain 2. *Work 1 LHDC in the next 6 stitches, LHDC2tog. Repeat from * around. Join. (Approximately 52 stitches)
2. Round 14 (Color D): Chain 2. *Work 1 LHDC in the next 5 stitches, LHDC2tog. Repeat from * around. Join. (Approximately 44 stitches)
3. Round 15 (Color D): Chain 2. *Work 1 LHDC in the next 4 stitches, LHDC2tog. Repeat from * around. Join. (Approximately 36 stitches)
4. Round 16 (Color D): Chain 2. *Work 1 LHDC in the next 3 stitches, LHDC2tog. Repeat from * around. Join. (Approximately 28 stitches)
5. Round 17 (Color D): Chain 2. *Work 1 LHDC in the next 2 stitches, LHDC2tog. Repeat from * around. Join. (Approximately 20 stitches)
6. Round 18 (Color D): Chain 2. *Work 1 LHDC in the next stitch, LHDC2tog. Repeat from * around. Join. (Approximately 14 stitches)
7. Round 19 (Color D): Chain 2. *LHDC2tog. Repeat from * around. Join. (Approximately 7 stitches)

Finishing

1. Fasten off, leaving a long tail (about 12 inches).
2. Thread the tail through a yarn needle.
3. Weave the needle through the remaining 7 stitches and pull tight to close the hole at the top of the crown.
4. Secure the yarn with a knot on the inside of the hat.
5. Weave in all ends securely using the yarn needle. Trim any excess yarn.

Your Aurora Borealis Slouch Hat is complete! The dense, woven texture and beautiful color transitions make this a truly special accessory. Wear it with pride, knowing you've created a piece that captures the magic of the northern lights. Happy crocheting!
