The slip stitch symbol in crochet charts

A filled dot. Adds no height, joins everything, and is the reason a round chart closes into a circle instead of spiraling.

What it looks like in a chart

A small solid dot — the smallest mark in the whole symbol set, which is exactly right, because a slip stitch adds essentially no height to the fabric.

On a chart worked in the round you will nearly always find a dot at the end of each round, sitting on top of the round’s first stitch. That is the join: it closes the ring so the next round starts from a known point rather than spiraling onward.

How it is used

Worth knowing

Both US and UK patterns call it a slip stitch. UK patterns often abbreviate it ss where US patterns write sl st; it is the same stitch.

The dot is easy to lose on a busy lace chart. If a round seems one stitch short when you count it, look for a dot tucked against the first stitch — joins are frequently drawn overlapping.

Common questions

What is the small filled dot on a crochet chart?

A slip stitch. It has almost no height, so it is drawn as a dot rather than a post. At the end of a round it marks the join back into the first stitch of that round.
