A slipknot is the loop you tie at the end of your yarn to start knitting

A slipknot is the first knot you make when you begin a knitting project. It creates a loop that slides onto your needle and holds your yarn in place while you cast on. The knot itself doesn't count as a stitch — it's just the anchor point. Once you've cast on all your stitches, you'll pull the slipknot tight so it sits snugly on the needle, and then you're ready to knit.

The slipknot takes about 10 seconds to tie once you know the motion. It's the same knot used in crochet, macramé, and many other fiber crafts, so learning it here means you'll recognize it everywhere.

Key Takeaways

  • A slipknot creates the loop that holds your first cast-on stitch and anchors your yarn to the needle.
  • You tie it by making a loop, pulling the working yarn through it, and then sliding the knot onto your needle.
  • The slipknot should be loose enough to slide onto your needle but tight enough that it won't fall off during casting on.
  • If your slipknot is too tight or too loose, you can untie it and start over — there's no penalty for practicing.

The four-step method to tie a slipknot

Hold the yarn in your hand with about 6 inches of the short end (called the tail) hanging down. Make a loop by crossing the working yarn (the long end coming from the ball) over the tail. The working yarn should pass over the top of the loop, creating an X shape.

Pull the working yarn through the loop from underneath. You now have a small loop with a knot forming at the base. This is your slipknot. Slide this loop onto your knitting needle so the knot sits just below the needle's tip.

Gently pull both the tail and the working yarn to tighten the knot around the needle. The knot should grip the needle firmly enough that it won't slide off, but loosely enough that you can still move it along the needle with your fingers. If it's too tight, loosen it slightly by pulling the tail away from the needle.

You're now ready to cast on. The slipknot counts as the first loop on your needle, though it won't become an actual stitch until you've completed your cast-on method.

Why the tension of your slipknot matters

If your slipknot is too tight, it will be hard to pull through when you knit your first row, and you may accidentally split the yarn or create an uneven first stitch. If it's too loose, the knot may slide off the needle before you've finished casting on, forcing you to start over.

The sweet spot is a knot that grips the needle without pinching the yarn. You should be able to slide the knot along the needle with gentle pressure from your fingers, but it shouldn't move on its own. As you gain experience, you'll develop a feel for this without thinking about it.

What to do if your slipknot doesn't feel right

If you've tied the knot and it feels wrong — too tight, too loose, or the loop is lopsided — straightforward untie it and start over. Pull the working yarn to undo the knot, and you're back to a plain piece of yarn. There's no cost to practicing, and getting the tension right from the start makes the rest of casting on much smoother.

Some knitters tie their slipknot directly on the needle, while others tie it in their hand first and then slide it on. Both methods work. Experiment to see which feels more natural to you. The knot itself is identical either way.

Common mistakes and how to avoid them

The most common error is making the loop too small. If your loop is tiny, the knot will be hard to work with and difficult to tighten evenly. Make sure the loop is large enough that you can comfortably pull the working yarn through it — roughly the size of a quarter or larger.

Another mistake is pulling the tail instead of the working yarn when tightening. The tail should stay relatively loose; it's the working yarn that does the tightening. If you pull the tail too hard, you'll create a knot that's difficult to adjust.

Finally, some beginners tie the knot and then when ready pull it very tight, thinking that's what "find" means. A slipknot doesn't need to be strangled. A firm grip is enough. You'll adjust the tension again as you cast on, so don't worry about making it perfect on the first try.

How the slipknot fits into your casting-on process

Once your slipknot is on the needle, you'll use your chosen cast-on method — long-tail, cable, or another style — to create the rest of your stitches. The slipknot is straightforward the foundation. As you cast on, you'll create new loops on the needle, and the slipknot will move along with them.

When you've finished casting on and are ready to knit your first row, the slipknot will be one of the stitches on your needle. You'll knit into it just like any other stitch, and it will become part of your fabric. By the time you've completed the first row, the slipknot is no longer visible as a separate knot — it's just the first stitch.

Frequently Asked Questions

Does the slipknot count as one of my cast-on stitches?

No. The slipknot is the anchor, and you count your cast-on stitches separately. If a pattern says to cast on 20 stitches, you'll have the slipknot plus 20 new loops on your needle. When you knit the first row, you'll knit all 20 cast-on stitches, and the slipknot will become your first stitch.

Can I tie the slipknot on the needle or should I tie it in my hand first?

Either method works. Tying it in your hand gives you more control over the tension, while tying it directly on the needle is faster once you're comfortable. Try both and stick with whichever feels easier to you.

What if I can't get the slipknot tight enough to stay on the needle?

Make sure you're pulling the working yarn (the long end from the ball), not the tail. Pull steadily and evenly on both sides of the knot. If it still won't grip, the loop may be too large — try making a smaller loop and tying again.

Is a slipknot the same in knitting and crochet?

Yes, the knot itself is identical. The only difference is how you use it — in knitting it goes on a needle, in crochet it goes on a hook. If you've learned a slipknot for one craft, you already know it for the other.

Do I need to tie a slipknot if I'm using a cast-on method that doesn't require one?

Most cast-on methods do start with a slipknot, but a few don't. Check your pattern or cast-on instructions. If they don't mention a slipknot, you can skip it and start directly with the cast-on method described.
