Step-by-Step Instructions
🧶 Back Panel:
-
Foundation:
Ch 85 (to fit medium bust; adjust in multiples of 6 + 1 for other sizes). Approx. 21” wide. -
Work Shell Stitch Pattern:
Begin Row 1 of shell pattern and continue to repeat the pattern until the back panel measures approximately 18–20 inches in height from shoulder to hem (or desired length). -
Shaping Shoulders (optional):
If desired, on the final 2 rows, you can decrease 1 shell on each side for shoulder tapering by skipping the first and last shell. -
Fasten off and block flat.
🧶 Front Panels (Make 2):
-
Foundation:
Ch 43 (half of back panel + 1 shell extra for overlap). You can ch more if you want the front to close or overlap more. -
Work Shell Pattern:
Repeat shell stitch pattern until length matches the back panel. -
Shape Neckline (Optional):
On the neckline edge (inner side), after approx. 10 inches in length, start decreasing 1 shell every 4th row to taper the edge slightly. -
Fasten off and block.
🧶 Sleeves (Make 2):
-
Foundation:
Ch 61 for elbow-length sleeves (approx. 15″ around). Add more chains for a looser or longer sleeve. -
Work Shell Pattern:

Optional Shaping:
Taper by decreasing 1 shell on each side every 3 rows to make a snugger fit at the elbow. -

🪡 Assembly:

Shoulders:
With right sides facing, seam the front panels to the back panel at the shoulders using whip stitch or mattress stitch. -
Attach Sleeves:
Mark the center of the sleeve and align it with the shoulder seam. Sew the sleeve to the armhole edge evenly. -
Side Seams and Underarms:
Fold garment at shoulders and seam sides and sleeve underarms, matching pattern lines as much as possible. -
Weave in all ends.
🌸 Scalloped Edging (Front, Neckline, and Hem):
This gives the beautiful decorative edging you see in the image.

-
Row 1 (Foundation edging):
Sc evenly around the entire front edge, neckline, and hemline. Place extra stitches around corners for a smooth curve. -
Row 2 (Scallop edging):
Sc in next st, skip 1, 5 dc in next st (scallop), skip 1, sc in next st, repeat around. Adjust as needed around corners. -
Fasten off and weave in ends.
💧 Blocking:
-
Lay the cardigan flat on a blocking board or towel.
-
Use pins to shape the scalloped edges evenly.
-
Steam lightly or wet block depending on your yarn.
📏 Sizing Tips:
-
For Larger sizes, add more chains in the foundation rows (increments of 6) and work additional rows in length.
-
For Smaller sizes, subtract chains in multiples of 6 and shorten the length accordingly.
-
Always check the gauge and customize for the best fit.
💡 Customization Ideas:
-
Add buttons or ties to the front for closure.
-
Use gradient or ombré yarn for a modern look.
-
Add longer sleeves for a full-sleeved version.
