Crochet Your Perfect Invisible Join

If you’ve ever crocheted in the round, you’ve probably noticed a common issue: the dreaded visible seam. That uneven line where the last stitch meets the first can be frustrating—especially when you want a neat, professional finish. Whether you’re making hats, motifs, coasters, or mandalas, that seam can really stand out in a not-so-good way.

This technique allows you to seamlessly close a round so that it blends in beautifully with the rest of your stitches. No more bulky slip stitches or strange “steps” between rounds. With just a few extra seconds, your work can look perfectly smooth—as if the round had no beginning or end.

Video guide

In the video tutorial below, I walk you through each step of how to crochet the Invisible Join. You’ll learn how to fasten off your last stitch, thread the tail, and weave it through the right loops to mimic a real stitch. It’s a tiny detail, but it makes a big difference.

I first included this method as part of my written and video instructions for the Derby Hat, where smooth round transitions are especially important for the brim and crown. But the Invisible Join works with any circular project and is especially useful for decorative pieces where every stitch counts.

Once you try it, I think you’ll find it hard to go back to the old way. It’s that clean and satisfying!

So grab your yarn and hook, and give it a go—your future round crochet projects will thank you.
