Slip Stitch and Invisible Finishing: Neat Edges and Seams
By The Slow Stitch · Terminology: US Crochet Terms · Reading time: 5 min read · theslowstitch.com
Slip stitches add little height and can join rounds or pieces of crochet. This lesson also introduces a needle join and weaving in ends. Finishing methods should suit the yarn and construction of the project.
What You'll Learn
By the end of this tutorial you will be able to:
- Make a basic slip stitch
- Practise an edging without puckering
- Finish an unjoined single-crochet round with a needle
- Weave in and check yarn tails
What You Need
Any scrap yarn for practice
Matching hook size
Bent-tip tapestry needle, Scissors
Use the materials above for practice, adjusting the hook if needed for comfortable stitches. For a finished project, follow its pattern’s yarn, gauge and care requirements.

The Basic Slip Stitch Movement
Insert your hook into the stitch. Yarn over and pull the loop through the stitch and directly through the loop on your hook in one smooth, continuous stroke. Do not tug the yarn tight afterwards.
Adding a Clean Slip Stitch Border
Practise slip stitches across the top of a swatch, placing one in each stitch without tightening them. Along row ends, placement depends on stitch height and gauge: lay the fabric flat frequently and adjust the spacing if it puckers or ruffles. There is no universal row-end ratio.
The Invisible Needle Join (Fastening Off in the Round)
For this example, finish an unjoined round of single crochet without making a slip stitch. Cut an 8-inch tail, pull the final loop up until the yarn end comes free, and thread it through a blunt needle.
Recreating the Top V
Skip the first sc of the round. Pass the needle under both top loops of the second sc. Bring it back into the top of the last sc, through the point where the tail emerged and under its back loop. Adjust the new strand to match the neighbouring stitch tops; it duplicates the top of the first sc. Other stitches and joined-round patterns may need a different finishing path.
The Three-Direction Weave
Weave the tail through the backs of several stitches, change direction, and weave through another section without pulling the fabric out of shape. Leave enough tail to secure it; slippery or bulky yarns may need a different method. Check the ends after the item is washed according to its care instructions.

Common Problems
| Problem | Cause | Fix |
|---|---|---|
| Slip stitch border is pulling the blanket into a tight bowl | Working slip stitches too tight or working into every row on the raw sides | Loosen the slip stitches, try a larger hook if needed, and adjust placement along row ends until the border lies flat. |
| The finish looks bulky | Adding a slip-stitch join before an invisible finish can add unwanted bulk | The needle-join example starts from an unjoined single-crochet round. Follow the finishing method specified for other constructions. |
| Yarn ends poke out after washing | Weaving in only one straight line | Always change direction at least twice when weaving tails. |
Frequently Asked Questions
Can you crochet an entire project with slip stitch?
Yes, Bosnian crochet uses almost entirely slip stitches worked into the back loop. It produces a thick, stretchy fabric that feels like thermal underwear.
What is surface slip stitch?
Holding your working yarn beneath your fabric and pulling loops up through the stitches allows you to draw lines, letters, or designs directly onto finished work.
Does slip stitch have a height?
No official height. It is considered flat, which is why it is used to transition between rounds or move across stitches without adding bulk.
Should I tie a knot before weaving in tails?
A knot alone is not a substitute for securing a tail. Weave the tail with changes of direction and check that the method suits the yarn, fabric, and intended use.
