What is slip stitch
Slip stitch (abbreviated sl st) is the lowest and most compact crochet stitch. Unlike single or double crochet, it adds no height — it only moves the hook to a new position. It's essential for joining, transitions between rounds, and finishing work.
Although slip stitch is simple, its uses are surprisingly wide — from closing magic rings to decorative surface crochet to entire projects crocheted exclusively with slip stitches (slip stitch crochet).
How to crochet slip stitch — instructions
Step 1: Insert hook
Insert the hook into the stitch you want to crochet into.
Step 2: Yarn over and pull through
Yarn over and pull through both the stitch AND the loop on your hook — in one motion. One loop remains on the hook. Done.
That's it — slip stitch is the simplest stitch. One step after inserting the hook.
Where slip stitch is used
Joining in the round
When crocheting in the round (granny squares, hats, amigurumi), at the end of each round you join the last stitch to the first with a slip stitch. Insert the hook into the first stitch of the round, make a slip stitch — the round is closed.
Moving to a new position
If you need to move the hook to a different position in the row without adding height, slip stitch across. Common when creating complex patterns or shaping necklines.
Invisible seam
You can join two finished pieces with slip stitches — place them together (right sides facing) and crochet slip stitches through both layers. Creates a clean, low-profile seam.
Surface slip stitch
You can crochet slip stitches on the surface of a finished piece — insert the hook through the completed fabric, pull yarn from back to front and crochet slip stitches across the surface. Creates lines, ornaments, letters, or geometric patterns. Excellent decorative technique.
Slip stitch crochet — entire projects
There's a specific technique where entire pieces are crocheted exclusively with slip stitches. The result is extremely dense, stretchy fabric resembling knitting. Used for hats, bands, and socks. Requires more yarn (high consumption) but the result is unique.
Slip stitch vs. single crochet
| Property | Slip stitch (sl st) | Single crochet (sc) |
|---|---|---|
| Height | Nearly zero | Low |
| Pull through | 1 step (all at once) | 2 steps |
| Main purpose | Joining, moving | Creating texture |
| Texture | Very dense, firm | Dense but flexible |
Tips
Don't crochet slip stitches too tightly — they'll be stiff and immobile. Maintain even, slightly looser tension. For joining slip stitches (at the end of rounds), make sure the join isn't visible — pull the yarn through smoothly without jerking.
