Ever been frustrated by the visible seam that forms when you slip stitch to join crochet rounds? Whilst working in continuous spirals (the amigurumi method) has its advantages, there are times when joined rounds are the better choice.
Joined rounds keep the height of each round even and are especially useful when you want symmetrical shaping or crisp edges. The problem? Traditional slip stitch joins often leave a noticeable “ladder” seam running through your work.
The solution: the seamless (invisible) join. This simple technique prevents the seam from showing, keeping your crochet neat, smooth, and professional-looking.

Why You will Love the Seamless Join
What is a Seamless Join?
A seamless join is a method of closing a round in crochet that avoids the bulky, stepped seam created by slip stitches. Instead of pulling up a slip stitch, you use your working loop to “mimic” the top of a stitch, blending the join invisibly into the round.
This technique is best used used mid-project (to move cleanly from round to round).
When to Use
- Hats, blankets, motifs, and decor: whenever symmetry matters.
- Amigurumi with joined rounds: perfect when spirals won’t do.
- Garments worked in the round for a perfect finish from every angle.
- Colour change rounds: for crisp, uninterrupted stripes.
Traditional Slip Stitch Join vs Invisible Join
Slip Stitch Join
Noticeable step at each round
Visible diagonal seam running through work
Slight ridge; can distort shape
Invisible Join
Smooth, continuous finish
Seamline disappears
Even, round shape; professional look
Photo Tutorial: How to crochet a Seamless Join
Step One: Finish your final stitch
Complete the last stitch of the round as normal. Draw up your loop slightly and remove the hook.
Step Two: Re-insert hook from back to front
Insert your hook into the stitch you want to join to (normally the first stitch of the round), back to front, with the hook facing your final stitch.
Step Three: Pull through the Final Loop
With the wrong side facing, place the final loop back on the hook, tighten gently and pull through.
Step Four: Realign hook
Remove the hook carefully, ensuring you don’t twist the loop. Reinsert in the correct direction to continue the next round.

Pattern Notes
- The ch1 at the start of each round does not count as a stitch. As such the first stitch of the round should be worked into the base of the chain. Do not turn.
- Stitches are made into both loops of the stitch below.
- Total stitch count is shown at the end of the round in brackets []
Practice Pattern
Rnd 1: Work 6dc into MR, join. [6]
Rnd 2: Ch1, 2dc in each st, join. [12]
Rnd 3: Ch1, (Dc in next st, 2dc in following st) x 6, join. [18]
Rnd 4: Ch1, dc in next st, 2dc in following st, (dc in next 2sts, 2dc in following st) x 5, dc in final st, join. [24]
Rnds 5: Ch1, (Dc in next 3sts, 2dc in following st) x 6, join. [30]
Rnd 6: Ch1, dc in next 2sts, 2dc in following st, (dc in next 4sts, 2dc in following st) x 5, dc in final 2 sts, join. [24]
Fasten off and weave in ends, admire your seam-free finish.
Trouble Shooting and Pro Tips
Twisting loops? Keep your hook flat as you are pulling through the join and make sure you are removing your hook to realign on the final step (do not just turn the hook)
Small bump at join? Loosen your final stitch slightly before joining and be careful not to tighten to much after you pull through.
Still seeing a seem? Double check that you’re inserting back-to-front through both loops of the stitch.
Uneven height? Always join to the the top of the first stitch, not the starting chain (unless the pattern specifies otherwise)
