Step-by-Step Pattern

STEP 1: MAKE THE PANELS

a. Sizing Your Panels

• Decide the final length of your cardigan (e.g., 24 inches).
• Large Panels: Make two panels, each twice the desired cardigan length (48 inches long), and of desired width (e.g., 10 inches).
• Small Panel: One horizontal panel (e.g., 24 inches long, 4 inches wide).

b. Foundation Double Crochet

• Make a slip knot.
• Chain 4.
• Yarn over, insert the hook into the first chain (through both loops), yarn over, pull through (3 loops), yarn over, pull through one loop (to create the chain), yarn over, pull through two loops (twice) to finish the first foundation double crochet.
• Continue foundation double crochet stitches until your row measures the required length – always work in multiples of three for the panel width.

c. Row 1 (Foundation)

• The first row is your foundation double crochet row.

d. Row 2 (Cluster Stitch Row)

• Chain 1, turn.
• Single crochet in first stitch. In the front loop of the V just made, single crochet again (to keep edge straight).
• Skip the next stitch. In the next stitch, work a 4-dc cluster as follows:
  • [Yarn over, insert in stitch, yarn over, pull through — 2 loops, yarn over, pull through 2 loops] four times (working in the same stitch), leaving each last loop on hook.
  • You will have 5 loops on the hook. Yarn over and pull through all 5 loops.
  • Chain 1 to close.
• Chain 1 again (makes “chain 2” after each cluster).
• Repeat: skip 2 stitches, cluster in next, chain 2.
• End with a double crochet in the final stitch.

e. Row 3 (Double Crochet Row)

• Chain 1, turn.
• Single crochet in the first stitch, work 1 double crochet in the front loop of the first single crochet for a straight edge.
• Double crochet in each chain space and on top of each cluster as follows:
  • DC in the chain-1 space following a cluster,
  • DC on top of each cluster,
  • 2 DC in each chain-2 space.
• Repeat to the end of the row.

f. Repeat Pattern

• Alternate Row 2 (cluster) and Row 3 (double crochet) for desired width.
• Make two of these large panels.
• Make one smaller horizontal panel as above (4 inches wide, 24 inches long or to your cardigan’s back width).

STEP 2: JOIN THE PANELS

• Lay the small panel between the tops of the two large panels (like a bridge).
• Sew the horizontal panel to the top of both large panels.
• Fold large panels in half, forming cardigan shape.
• Sew sides partially to form the body, leaving space for armholes.

STEP 3: BORDERS

a. Cardigan Border

• Starting at any edge, attach yarn and work a round of single crochet evenly around all edges (neck, front, and bottom).
• For each join or corner, make extra stitches as needed for a smooth curve.

b. Sleeve Border

• Join yarn at armhole.
• Work a round of single crochet. Join with a slip stitch.
• For the desired sleeve length/effect, work 6–7 rounds of single crochet in the back loop only to create a ribbed texture.
• Each round: chain 1, single crochet in the back loop of every stitch.
• Join each round with a slip stitch.

STEP 4: Finishing

• Weave in ends neatly.
• Block cardigan gently if desired for a polished look.

Tutor’s Suggestions

• Foundation double crochet creates flexible, stretch-resistant edges.
• Count your stitches for symmetry—especially when sewing panels.
• When making borders/sleeves, crochet in the back loop for gorgeous texture.
• Try the cardigan on as you work to adjust your armhole and body fit.
