Let's dive into everything you'll need to create this stunning cocoon cardigan.

Materials Needed

Before you begin, gather the following supplies to ensure a smooth and enjoyable crochet experience:

• Yarn: Worsted weight (Category 4) yarn in teal. You'll need approximately 1200–1500 yards for sizes S/M. Adjust the yardage accordingly if you're making a different size. A rich jewel-toned teal works beautifully, but feel free to choose any color that speaks to your personal style.
• Crochet Hook: US Size I/9 (5.5 mm) crochet hook. This hook size pairs perfectly with worsted weight yarn to create a dense, cozy fabric with good drape.
• Yarn Needle: A tapestry or yarn needle for weaving in ends and finishing.
• Stitch Markers: A few stitch markers to help you keep track of rounds and important stitch placements, especially when working the armholes and sleeves.

Gauge: 14 dc x 8 rows = 4 inches (10 cm) in shell stitch pattern (after blocking). Achieving the correct gauge is essential for a properly fitting jacket. If your gauge is off, adjust your hook size up or down accordingly.

Step-by-Step Instructions

This pattern is designed to be beginner-friendly, but it does involve some intermediate techniques like shell stitches and working in the round. Don't worry—the instructions below are detailed and easy to follow. Let's get started!

Pattern Notes

• The pattern is worked in one piece from the top down, then sleeves are added.
• Ch 3 counts as dc throughout the pattern.
• Shell stitch (shell): (2 dc, ch 1, 2 dc) in same stitch or space.
• The pattern is written for size S/M. To adjust for other sizes, chain in multiples of 6 + 4 for the foundation chain.

Body (Worked Flat)

Row 1: Ch 82 (for S/M; adjust by multiples of 6 + 4 for other sizes). Dc in 4th ch from hook and in each ch across. Turn. (80 dc)

Row 2: Ch 3, skip next 2 dc, shell in next dc, *skip next 2 dc, shell in next dc* repeat from * to * across, skip last 2 dc, dc in top of turning ch. Turn. (16 shells)

Row 3: Ch 3, shell in each ch-1 space across, dc in top of turning ch. Turn. (16 shells)

Rows 4–25: Repeat Row 3. This forms the back and front panels. At the end of Row 25, do not turn.

Tip: As you work these rows, you'll see the shell stitch pattern emerge beautifully. The fabric will grow quickly, and the repetitive nature of the stitch makes it a relaxing, meditative project. Use stitch markers at the edges if you find it helpful to keep track of your rows.

Shape Shoulders

Row 26: Ch 3, shell in next 4 ch-1 spaces (front right), ch 3, skip next 6 shells (armhole), shell in next 6 ch-1 spaces (back), ch 3, skip next 6 shells (armhole), shell in next 4 ch-1 spaces (front left), dc in top of turning ch. Turn. (14 shells total)

Row 27: Ch 3, shell in each ch-1 space across, working 2 shells in each ch-3 space (armhole edges), dc in top of turning ch. Turn. (18 shells)

Rows 28–40: Repeat Row 3. Fasten off.

Note: The ch-3 spaces you create in Row 26 will become the armholes. When you work 2 shells into each ch-3 space in Row 27, you're creating the foundation for the sleeves. This clever construction method ensures a seamless transition from body to sleeves.

Sleeves (Make 2, Worked in the Round)

Round 1: Attach yarn at underarm, ch 3, work 2 dc in same space, shell in each ch-1 space around armhole, join with sl st to top of ch 3. (18 shells)

Rounds 2–20: Ch 3, shell in each ch-1 space around, join with sl st to top of ch 3. (18 shells)

Round 21: Ch 2 (does not count as hdc), hdc in each dc and ch-1 space around, join with sl st to first hdc. Fasten off.

Tip: When working in the round, place a stitch marker at the beginning of each round to help you keep track of where you started. The sleeves are worked from the armhole down, so you'll be crocheting in a spiral-like fashion with joined rounds. The hdc edging in Round 21 gives the sleeves a neat, finished cuff.

Finishing

Weave in all ends using your yarn needle. This step is crucial for a polished, professional-looking finished piece. Take your time to weave in ends securely, especially at the underarm seams and where you fastened off.

Block to measurements. Blocking is essential for this pattern—it helps the shell stitch open up and drape beautifully. To block, gently wet the jacket with lukewarm water, squeeze out excess moisture (don't wring!), and lay it flat on a blocking mat or towel. Shape it to the desired measurements and pin it in place. Allow it to dry completely before removing the pins.

Optionally, add a crochet edging of sc around the front opening and bottom hem for a cleaner finish. This simple border adds structure to the edges and gives the jacket a more polished look. To do this, attach your yarn at any point along the edge, ch 1, and work sc evenly around the entire front opening and bottom hem. Join with a sl st to the first sc and fasten off.

Final Thoughts

Your Terrifically Teal Crochet Jacket is now complete! This boho cocoon cardigan is the perfect layering piece for cool evenings, breezy mornings, or anytime you want to add a handcrafted touch to your outfit. The rich teal color and textured shell stitch make it a standout piece in any wardrobe.

This pattern is wonderfully versatile—feel free to experiment with different yarn colors, from earthy neutrals to vibrant jewel tones. You can also adjust the length by adding or removing rows in the body section, or make the sleeves longer by adding more rounds.
