Crochet seaming brings pieces together, but seams can also be decorative and worked into the visual design of a project. There are dozens of ways to join crochet fabric. I’m sharing 4 of my favorite methods here. Each one has its benefits and drawbacks. But I always find that no matter what seam I am going for, one of these four will fit the bill.

Regardless of the function your seams play, tension is the most important piece of the puzzle. Work your seams too tight and your crochet fabric will group and bunch. Work the seam too loose and your work will have gaps where the seams should be. Be mindful of your tension throughout the seam and don’t be afraid to unpick part of your seam and redo it to achieve a clean seam.

What You Will Learn

Many crochet projects from sweaters to blankets, amigurumi, and shawls will involve crochet seaming. This video will teach you 4 simple techniques that are easy for beginners to pick up on and use in their projects. Even as an experienced crocheter, I go back to these techniques again and again.

  • Whip Stitch Seam: fast, easy, medium strength seam. Good for most seaming needs.
  • Mattress Stitch Seam: time consuming, strongest seam with minimal flexiblity. Great for garment seams under arm and at shoulder.
  • Single Crochet Seam: slightly textured and mostly invisible. Great universal seaming technique when the wrong side of work is hidden.
  • Flat Slip Stitch Seam: lovely, decorative seam when worked in a complimentary or contrasting color. Ideal for blankets.

What You Need For Crochet Seaming

Crochet seaming uses the notions you have on hand already. Hand-sewn seams can be worked with a tapestry needle. I prefer metal, as they glide cleanly through crochet fabric and won’t split the yarn. Keep scissors handy too, to cut the yarn before and after completing your seam. A crochet hook is needed for stitched seams, but not for hand-sewn seams.

    I’ve been SO looking forward to the finishing and seaming topics! I’m not new to crocheting, but had been away for a over 25 years and in my previous “crochet life” never did any blocking, and only used single crochet for seaming. Thank you for helping me to step up my game! Can’t wait to use these techniques with the upcoming CALs!!!

    Oh this is great! I’ve always only slip stitch seamed, but I tended to struggle with puckering. It’s nice to have alternatives!

    Whoa! Watched the video and thought the mattress seam was looking too complex. Decided to try anyway… pulling those ends and watching the bright purple yarn become INVISIBLE somehow between the 2 light blue granny squares was like absolute magic! Even my 21-year-old son was impressed!

    Excited to try these! What’s your preferred method for securing the ends after joining two pieces?

    Excellent video, as expected! A couple of questions. First, when the stitches you are joining are chain stitches, are you “going around” the chain, or going between the top Vee of the chain and the back bump? Also, the joins you demonstrated are between the “tops” of stitches. How does one join the EDGES of crochet pieces? My edges seem to consist of chains and “bumps”. The bumps are generated when a turn is made with single crochet stitches. There is the final loop of the last sc, the chain one, and when turned and the hook inserted into the first space, the final loop has become a “bump” on the edge. Perhaps there is something i am not doing correctly?

    Thank you for the instructions. I’ve only done blankets so I’ve never had to do seams. The mattress stitch seam and the flat slip stitch seam were a little too much for me. I can see myself frogging a lot with those but the whip stitch seam and the single crochet stitch seam will be my go to’s. As always you’re a wonderful instructor.
