How to Crochet the Shell Stitch

The shell stitch is one of the prettiest beginner-friendly stitch patterns. A “shell” is simply a group of double crochets (dc; UK treble) worked into one stitch, so they fan out. Alternate shells with single crochets (sc; UK double crochet) and you get a scalloped fabric that’s lovely for blankets, scarves and borders.

US/UK note: this page uses US terms. US dc = UK treble (tr); US sc = UK double crochet (dc).

You’ll need

• Worsted-weight yarn and a matching hook (5 mm / H-8)
• Confidence with chain, single crochet and double crochet

Shell sizes

A shell can have 3, 4, 5, 6 or more stitches. This page uses the common 5-dc shell: 5 double crochets in the same stitch. Patterns with larger shells skip more stitches on either side of each shell (see Variations below).

Foundation multiple

Chain a multiple of 6 + 2. For a swatch with 4 shells, chain 26 (6 × 4 + 2).

Abbreviations

• ch: chain · sc: single crochet · dc: double crochet · sk: skip
• shell: 5 dc in the same stitch
• half shell: 3 dc in the same stitch (used at the edges, counting the turning chain as one)

Step-by-step: shell stitch in rows

Row 1: Sc in 2nd ch from hook, *sk 2 ch, 5 dc in next ch, sk 2 ch, sc in next ch; rep from * across, turn. (4 shells, 5 sc)

Row 2: Ch 3 (counts as dc), 2 dc in first sc (half shell made), *sk 2 dc, sc in next dc (the center dc of the shell), sk 2 dc, 5 dc in next sc; rep from * across, ending the last repeat with 3 dc in the last sc instead of 5, turn. (3 full shells, 2 half shells, 4 sc)

Row 3: Ch 1 (does not count as a st), sc in first dc, *sk 2 dc, 5 dc in next sc, sk 2 dc, sc in next dc (center of the shell); rep from * across, working the last sc in the top of the turning ch, turn. (4 shells, 5 sc)

Repeat Rows 2–3 for the pattern.

How to make one shell

1. Skip the number of stitches the pattern says (here, 2).
2. Work 1 dc in the next stitch.
3. Work 4 more dc into the same stitch — insert into exactly the same place each time.
4. Skip 2 and work the next sc. That sc anchors the shell between its neighbors.

Tip: Find the center of a 5-dc shell by counting: it’s the 3rd dc. The sc in the next row always goes there, so the new shells nest neatly between the old ones.

Why the half shells?

Shells in Row 2 sit on top of the single crochets from Row 1, which means they’re offset by half a repeat. At the edges there isn’t room for a full shell, so a half shell fills the gap: ch 3 plus 2 dc at the start of the row, and 3 dc in the last sc at the end. Published shell-stitch tutorials use half shells this way so the row is as wide at its ends as the full shells are, rather than leaving a dip at each side.

Common mistakes

• Wrong foundation count. If your last repeat doesn’t end on an sc, recount your chain — it must be a multiple of 6 + 2.
• Spreading shell stitches across two chains. All 5 dc go into the same stitch.
• Not skipping 2. Without the skips, the shells crowd together, the stitch count grows and the fabric can ruffle.
• Missing the center dc. Placing the sc off-center shifts the next row’s shells out of line. Count to the 3rd dc.
• Forgetting the turning chain on Row 3. The last sc goes into the top of the ch-3 from Row 2.

Variations

Variation	What changes
3-dc shell	Sk 1, 3 dc in next, sk 1, sc — multiple of 4 + 2
7-dc shell	Sk 3, 7 dc in next, sk 3, sc — multiple of 8 + 2
V-shell	(2 dc, ch 1, 2 dc) in one stitch for a lacier look
Shell border	Work a single row of shells around a finished blanket edge

FAQ

What is a shell in crochet?

A group of three or more taller stitches, usually double crochets, worked into one stitch or space so they fan out like a shell.

How many chains do I need for shell stitch?

For the 5-dc shell pattern on this page, a multiple of 6 + 2. For example, 20, 26 or 32 chains.

Why are my shells ruffling or cupping?

First check the multiple and the skip counts against the pattern: skipping too few stitches crowds the shells, and a mismatch between shell size and skips changes the fabric. If the counts are right, a tight foundation chain or tension that differs from the pattern’s gauge can also distort the first rows, so try a larger hook for the chain or a different hook size overall.

Is shell stitch easy for beginners?

Yes — if you can double crochet and count to five, you can make shells. The only new idea is putting several stitches into one place.
