About this pattern

Arcade stitch is a two-row repeat: a single crochet foundation row worked into back bars, followed by a shell row of 7-double-crochet fans separated by skipped stitches and single crochets. The chain must total a multiple of 6 plus 2 for the shells to land correctly across the row. Expect open, visible shell texture suited to scarves, wraps, or blanket panels, with every repeat checkable against the 7-dc count.

The arcade stitch pairs a plain single crochet foundation row with a shell row built from 7-double-crochet fans, skipped stitches, and single crochet spacers. Work the foundation into the back bars of a chain in multiples of 6 plus 2 for a clean edge, then turn and repeat the 7-dc shells into each chain space across. The count that matters most is the chain multiple: get the 6-plus-2 math wrong and the shell spacing falls out of alignment by the last repeat.

The pattern

Written out round by round

Materials

Worsted weight yarn
Crochet hook (size to suit your yarn)

Abbreviations

sc = single crochet
dc = double crochet

Chain

Work a chain in multiples of 6, then add 2 additional chains.

Example: If you chain 18 (which is 6 x 3), then add 2, totalling 20 chains.

Round 1Turn Work: After your chain, turn your work to start the first row.

End

Upon reaching the end, after the last pattern repeat, you'll have two chains left. Single crochet into each of these last two chains.

Round 2Turn Work: Chain one and turn your work. First Chain Space: In the first chain space, work 7 double crochets (dc).

End

After the last repeat, chain one and double crochet into the final stitch.

Round 4Start: Chain three (counts as a double crochet) and turn your work. Chain Space Work: In the immediate chain space, work three double crochets.Skip and Single Crochet: Skip a stitch, then work a single crochet in the next stitch.Continue the pattern across, finishing with four double crochets in the final chain space.

Round 5Start: Chain one and turn your work.

Start Stitching

Skip one chain, single crochet (sc) into the second chain from the hook.

Pattern Repeat: Single Crochet: Do another single crochet in the next stitch.

Chain 3: Then chain three.

Skip 3 Stitches: Skip the next three stitches on the chain.

3 Single Crochets: Then do 3 single crochets in the following three chains.

Repeat this pattern (chain 3, skip 3, 3 single crochets) across the row.

Initial Single Crochets

Single crochet into the first and second stitches.

Pattern Repeat: Chain three, skip five stitches, work three single crochets, repeating across.

Tester's notes

7 double crochets per shell is the only count that confirms the row is on track; miscount once and every shell after it shifts.

2 chains remain at the end of the foundation row — work a single crochet into each one before turning, not just one.

6-stitch multiples, plus 2, set the chain length; recount the chain before the first row rather than after the first shell row is underway.

1 skipped stitch separates each shell from its single crochet; skipping two by mistake collapses the open spacing that defines the stitch.

1 chain turn between rows is all this pattern uses — extra chains at the turn add unintended height to alternating rows.

Gauge check

After the first shell row, count the double crochets in one fan: each completed chain space should hold exactly 7, not 6 or 8.

If the count is off, pull back to the last correct chain space and rework from there rather than adjusting tension further down the row.

If something looks wrong

The shells along the row are uneven widths.: Caused by inconsistent stitch count inside the chain spaces; recount to 7 double crochets per space and rework any space that reads 6 or 8.
The fabric edge ripples instead of lying flat.: Usually comes from skipping an extra stitch or missing the skip between shells; confirm exactly 1 stitch is skipped before each single crochet and correct the row before continuing.
The last shell at the row end does not match the others.: Happens when the final two chains from the foundation row were not each given their own single crochet; go back and confirm 2 separate single crochets sit at the row end.
The piece narrows gradually across several rows.: Points to a chain that was not an exact multiple of 6 plus 2 at the start; recount the foundation chain and restart the row if the total does not divide evenly.

Yarn substitutions

Cotton, worsted weight	Produces a flatter, less springy shell with sharper stitch definition; the original hook size still fits since the weight matches, but drape stiffens and the 7-dc fans show more distinctly.
Acrylic, DK weight	Shells shrink and the overall piece narrows for the same chain count; move down a hook size to keep the fabric from going loose and open.
Wool-blend, bulky weight	Shells open wider and the fabric thickens fast, so fewer chain repeats are needed to reach the same width; move up a hook size to keep the 7-dc fans from packing tight.

FAQs

Questions

Why does the chain need to be a multiple of 6 plus 2?

The foundation row's single crochets and the shell row's 7-dc fans both depend on that exact math to repeat evenly across the row. Any other total leaves a partial shell or an uneven stitch count at one edge.

What happens if only 6 double crochets fit in a chain space?

The shell reads narrower than the rest and throws off the spacing for every shell after it. Pull back to that chain space and add the missing double crochet before moving on.

Can the 2 leftover chains at the row end be skipped instead of single crocheted?

No — both of the last 2 chains take their own single crochet to keep the row count consistent with the rest of the pattern. Skipping either one shortens the edge and misaligns the next row's turning chain.
