Quick Overview of Pattern

• Foundation: Chain 3, 1 double crochet repeated to create 77 eyelets for the base width.
• Shell Stitch Panels: Build front and back panels with classic shell stitch clusters (2 dc, ch 2, 2 dc) alternating with chain spaces and strategic single and double crochets.
• Armhole Shaping: Place stitch markers at 11th shells from each side to define underarm zones and work front decreases accordingly.
• Panel Joining: Seamlessly join front and back panels using slip stitches.
• Sleeves: Crochet sleeves in the round, transitioning from double crochets into the shell pattern, with rounds for cuff shaping and edging.
• Borders & Front Tie: Complete with bottom shell stitch border and a separate front tie strip, finished with coordinated edging for a cohesive look.

---

Notes

• The pattern uses US crochet terminology.
• Maintain consistent gauge to ensure even shaping and fit.
• Stitch markers are vital for underarm definition and smooth panel transitions.
• The cardigan is worked in panels and then joined with slip stitches to avoid bulky seams.
• Sleeves are made in the round, simplifying shaping and joining.
• The front tie is created separately to match edging motifs and sewn or crocheted on after assembly.

Skill Level

Intermediate

This project requires:

• Familiarity with fundamental stitches: chain (ch), double crochet (dc), single crochet (sc), slip stitch (sl st).
• Skill in working shell stitch motifs.
• Experience managing stitch markers and shaping via stitch count adjustments.
• Ability to join panels neatly with slip stitches.
• Working in rounds for sleeves.

---

Materials

• Three-ply cotton yarn, approximately 350–400 grams depending on size and length.
• Crochet hook size 2.5 mm.
• Stitch markers (at least 4).
• Yarn needle for sewing ends and assembling.
• Scissors.
• Measuring tape for sizing checks.

---

Measurements / Sizing (Optional Schematic)

• The cardigan’s base width uses 77 eyelets, suitable for a medium size adult garment.
• Length and sleeve circumference can be adjusted by working additional rows or rounds.
• Placement of markers at the 11th shell from both edges creates armholes proportional to the frame size.
• Blocking after assembly will enhance drape and final fit.

---

Gauge and Stitch Pattern

• Gauge is approximate and depends on individual tension; consistent working preferable to maintain garment integrity.
• Shell stitch pattern consists of:
  • Clusters of 2 double crochets, chain 2, 2 double crochets in the same space, separated by chain spaces or single double crochets as defined per row.
• Pattern rows alternate shells with chain or dc stitches, creating an attractive lace effect.

ch	chain
dc	double crochet
sc	single crochet
sl st	slip stitch

Special Stitches

• Shell Stitch (Shell Cluster): Work 2 double crochets, chain 2, then 2 double crochets all in the same stitch or chain space—creating a fan or shell shape.
• Panel Join Slip Stitch: Joining front and back panels by slip stitching through respective stitches for a flat seam.
• Marker Placement: Used on the 11th shell clusters to define armhole boundaries and support shaping.

The Crochet Pattern – Step by Step

1. Foundation Chain (Create Base Row)

• Chain a multiple of 2 plus 1 to get 77 eyelets total.
• To do this:
  • Chain 3 (this counts as your first double crochet)
  • Then repeat:
    • Chain 3
    • 1 double crochet (dc)
  • Continue this until you have created 77 eyelets total (count the number of “chain 3” spaces carefully).

---

2. Main Panel Construction – Shell Stitch Rows

Row 1 (Start Shell Pattern)

• Chain 3 (counts as first double crochet).
• In the same space:
  • Work 2 double crochets (dc)
  • Chain 2
  • Work 2 double crochets (dc) again — this forms the first shell.
• Then:
  • Work 1 double crochet in the next eyelet space.
• Repeat this sequence across the row:
  

  Shell (2 dc, ch 2, 2 dc) → 1 dc in next eyelet

Continuing Rows

• Keep repeating the shell pattern for both front and back panels.
• Maintain consistent shell shapes and spaces.
• Work evenly until you reach the desired length or the count for the shaping step.

---

3. Marker Placement for Armholes

• Identify the 11th shell from the left and the 11th shell from the right.
• Place stitch markers on the double crochet stitches on these shells to mark the underarm positions.
• These markers will help guide the shaping for the cardigan’s sides.

---

4. Decrease Shaping & Body Construction

Decreasing on Front Panels

• Beginning from the markers inward, gradually decrease stitches by modifying shell placement as follows:
  • Change how many shells or double crochets are worked near sides to reduce width and shape armhole edges.
  • Keep the shell motif balanced, adjusting carefully around markers.

Continuing Rows

• Work 16 rows maintaining the armhole side straight (no decreases) to shape the armhole smoothly.
• Complete a total of 23 rows on the front panels.

Back Panel

• Work the back panel straight (no decreases) between the stitch markers for 22 rows.
• Save the 23rd row for joining front and back panels.

---

5. Joining the Panels

• Use slip stitches (sl st) to join front and back panels at the sides and shoulders smoothly.
• Ensure stitches line up; join along the edges marked for armholes to create flat seams with no bulk.

---

6. Sleeves Construction (Worked in the Round)

Starting the Sleeve

• Begin with:
  • Chain 3 (counts as first dc)
  • Work 1 double crochet (dc) in the following stitch/space.
• Join ends with a slip stitch to form a ring.

Working the Shell Pattern on Sleeves

• Continue to work the shell stitch as follows around the sleeve:
  • 2 dc, ch 2, 2 dc in one space (shell)
  • Chain and single dc spaces as previously established.
• Work 20 rounds of the shell stitch.

Modified Shell Stitch & Cuffs

• Follow with 6 rounds of a modified shell stitch for sleeve shaping and texture variation.
• Finish cuffs with a decorative edging (for example, smaller shells or simple sc rounds).

---

7. Bottom Border

• Attach yarn to the cardigan’s bottom edge.
• Work 18 rows of the shell stitch pattern to create a matching border.
• Finish the border with a final round of 10 double crochets inserted into single crochet stitches for a neat finish.

---

8. Front Tie Band

• Chain a foundation to create 50 eyelets:
  • Chain 3 (counts as first dc), then repeat chain 3, 1 dc until 50 eyelets formed.
• Work the tie using the shell stitch and single crochet border pattern matching the cardigan’s edges.
• Attach securely along the front edges of the cardigan.

---

Assembly & Finished Size

• Finish joining all pieces carefully; weave in ends snugly.
• Steam block or lightly wet block the cardigan to flatten stitches and help aligning motif patterns.
• The finished cardigan fits a medium frame, with adjustable length and sleeve circumference by modifying rows or stitch counts.
• The seamless joins and balanced shell stitches ensure a well-structured garment with soft drape.
