Step-by-Step Crochet Instructions

Back Panel

Foundation:
Ch 85 (medium bust, ~21” wide). Adjust in multiples of 6 + 1 for other sizes (e.g., 79 for small, 91 for large).

Work Shell Pattern:
Follow Row 1 of shell stitch pattern, then repeat Row 2 until panel measures 18–20” from shoulder to hem (or desired length).

Optional Shoulder Shaping:
For a tailored fit, decrease 1 shell on each side in the final 2 rows by skipping the first and last shell.

Finish: Fasten off and block flat to set stitches.

Front Panels (Make 2)

Foundation:
Ch 43 (half of back panel + 1 shell for overlap, ~10.5” wide). Add more chains for greater overlap or a closed front.

Work Shell Pattern:
Repeat shell stitch pattern until length matches back panel (18–20”).

Optional Neckline Shaping:
After ~10”, decrease 1 shell every 4th row on the inner (neckline) edge to create a subtle taper.

Finish: Fasten off and block.

Sleeves (Make 2)

Foundation:
Ch 61 for elbow-length sleeves (~15” around). Add chains in multiples of 6 for looser or longer sleeves.

Work Shell Pattern:
Repeat shell stitch pattern until sleeve measures 8–10” (or desired length).

Optional Shaping:
Taper sleeves by decreasing 1 shell on each side every 3 rows for a snug elbow fit.

Finish: Fasten off and block.

Assembly

Shoulders:
With right sides facing, seam front panels to back panel at shoulders using whip stitch or mattress stitch for a clean finish.
Sleeves:
Mark sleeve center and align with shoulder seam. Sew sleeves to armholes, ensuring even distribution.
Side Seams & Underarms:
Fold cardigan at shoulders. Seam sides and sleeve underarms, aligning shell patterns for a polished look.
Weave Ends: Use a yarn needle to secure all loose ends.

Scalloped Edging

This decorative trim enhances the cardigan’s elegance, framing the front, neckline, and hem.

Attach Yarn: Start at the bottom right front edge.
Row 1 (Foundation): Sc evenly around front edges, neckline, and hem. Add extra sc at corners for smooth curves.
Row 2 (Scallop): Sc in next st, skip 1, 5 dc in next st (scallop), skip 1, sc in next st. Rep around, adjusting at corners.
Finish: Fasten off and weave in ends.

Blocking

Blocking enhances the lacy texture and ensures even scalloped edges.

Lay cardigan flat on a blocking board or towel.
Pin edges to desired shape, emphasizing scallops.
Steam lightly or wet block (depending on yarn). Allow to dry completely.

Sizing Tips

Larger Sizes: Add chains in multiples of 6 to foundation rows (e.g., 97 for XL) and extend row counts for length.
Smaller Sizes: Subtract chains in multiples of 6 (e.g., 73 for XS) and reduce row counts.
Fit Check: Measure gauge swatch and compare to body measurements for a custom fit.

Customization Ideas

Closures: Add buttons, ties, or a crochet chain loop for a secure front.
Yarn: Use gradient, ombré, or metallic yarn for a modern twist.
Sleeves: Extend to full length for a cozy fall cardigan.
Edging: Experiment with picot or fan stitches for unique trim.
