Grafting creates an invisible seam by threading your needle through live stitches on two separate pieces, mimicking the row of knit stitches between them

Grafting, also called Kitchener stitch, joins two pieces of knitting without binding off first. Instead of casting off and then seaming the edges together with a visible line, you work directly into the live stitches — the loops still on your needles — and pull them closed. The result looks like a continuous knit fabric with no seam at all.

The technique works best on stockinette stitch (the smooth V-pattern side of knit fabric) and requires that both pieces have the same number of stitches on their needles. You will need a tapestry needle, yarn in the same weight and color as your project, and patience to keep the tension even as you work.

Grafting is most useful for joining the shoulders of a sweater, closing the top of a hat, or seaming the sides of a tube you have knit flat. It takes longer than binding off and seaming, but the invisible join is worth it for visible seams on fitted garments.

Key Takeaways

  • Grafting joins live stitches from two needles without binding off, creating a seam that looks like part of the knit fabric itself.
  • Both pieces must have exactly the same number of stitches, and the yarn should match your project in weight and color.
  • The basic pattern repeats four steps — two on the front needle, two on the back needle — until all stitches are grafted.
  • Tension matters: pull the yarn snug enough to close the gap but not so tight that the grafted row puckers or becomes stiff.
  • Grafting works best on stockinette stitch and is most visible on reverse stockinette or textured stitches, where you may prefer a traditional seam instead.

Set up your needles and yarn

Place both pieces on separate needles with the right side of the fabric facing you. The stitches should be live — not bound off — and the needle tips should point in the same direction (usually to the right). If one piece has been bound off, you will need to pick up the stitches along that edge with a crochet hook or needle before you can graft.

Thread your tapestry needle with a length of yarn about 18 to 24 inches long. Use the same yarn as your project if you have it; if not, match the weight and color as closely as you can. Tie a small knot at the end of the yarn, or straightforward hold the tail and weave it in later.

Position the two needles so they are parallel and close together, with the working yarn coming from the right side of the back needle (the one farther from you). This is your starting point.

Work the four-step pattern

Grafting follows a repeating four-step sequence that you will work across all the stitches. The steps alternate between the front needle (closer to you) and the back needle (farther from you).

Step 1 (back needle, knitwise): Insert your tapestry needle through the first stitch on the back needle from right to left, as if you were about to knit it. Do not drop the stitch from the needle yet.

Step 2 (back needle, purlwise): Insert the needle through the second stitch on the back needle from left to right, as if you were about to purl it. Again, leave the stitch on the needle.

Step 3 (front needle, purlwise): Insert the needle through the first stitch on the front needle from left to right, as if you were about to purl it. This time, slip the stitch off the needle.

Step 4 (front needle, knitwise): Insert the needle through the second stitch on the front needle from right to left, as if you were about to knit it. Leave this stitch on the needle.

Now go back to step 1 and repeat with the next pair of stitches on the back needle. You will drop one stitch from each needle with every complete cycle of four steps.

Manage tension as you graft

Pull the yarn snug after every two or three stitches so the grafted seam sits flush with the fabric and the gap between the two pieces closes. If you pull too hard, the grafted row will pucker and become stiff. If you do not pull hard enough, the seam will be loose and visible.

The tension should match the rest of your knitting — not tighter, not looser. A common mistake is to pull so hard that you distort the stitches on either side of the graft. Instead, pull just enough to close the gap and let the stitches settle into their natural shape.

If you notice the grafted row is too loose after you have finished, you can go back and tighten it by pulling on the yarn tail and working the slack back through the seam. This is easier to fix than a puckered seam, so err on the side of slightly loose if you are unsure.

Finish and weave in the yarn tail

Once you have grafted all the stitches, the two pieces will be joined and the live stitches will have become part of the grafted row. Pull the yarn tail snug one last time to even out the tension, then thread the needle through the tail of yarn and weave it into the seam or into the fabric nearby.

Weave the tail back and forth through the stitches for at least an inch, changing direction at least once so the tail does not pull out. Trim the excess yarn close to the fabric.

Turn the piece over and check the seam from the wrong side. The grafted row should look like a continuation of the knit pattern, with no visible line or bump.

Grafting on different stitch patterns

Grafting works most cleanly on stockinette stitch because the V-pattern of knit stitches is straightforward to follow and the seam blends in. On reverse stockinette (the bumpy side), garter stitch (horizontal ridges), or textured stitches, the grafted row may be more visible because the stitch pattern is less uniform.

If you are grafting a textured or reversible fabric, test the graft on a swatch first to see whether it will be noticeable. For some projects, a traditional three-needle bind-off or a backstitch seam may be a better choice than grafting.

On ribbed fabric (alternating knit and purl stitches), grafting is possible but tricky because you have to follow the knit-purl pattern as you work. Many knitters prefer to bind off and seam ribbed edges instead.

Common mistakes and how to fix them

The most common error is dropping a stitch accidentally while you are working. If you notice a dropped stitch before you have gone too far, pick it up with a crochet hook and pull it back up to the needle, then continue grafting. If you do not notice until later, you may need to unravel back to that point and start again.

Another frequent problem is working the steps in the wrong order or inserting the needle in the wrong direction. If the grafted row looks bumpy or twisted, you may have reversed a step. Unravel a few stitches, check your pattern, and try again.

If the grafted seam is too tight and puckers the fabric, or too loose and gapes, you can sometimes fix it by carefully pulling the yarn tail to redistribute the tension. If the problem is severe, unravel and re-graft that section.

Frequently Asked Questions

Do I have to bind off before I graft?

No. Grafting works on live stitches that are still on the needle. If one piece has already been bound off, you will need to pick up the stitches along that edge with a crochet hook before you can graft. This is more work than grafting two live edges, so plan ahead and do not bind off if you know you will be grafting.

Can I graft with a different yarn color?

You can, but the seam will be visible. If you must use a different color, match it as closely as possible to one of the two pieces you are joining. The graft will show less if the yarn color is close to the fabric than if it contrasts sharply.

What if the two pieces have different numbers of stitches?

You cannot graft pieces with unequal stitch counts. You will need to either adjust one piece by picking up or dropping stitches, or use a different joining method such as a backstitch seam or a three-needle bind-off.

How long does grafting take compared to binding off and seaming?

Grafting takes longer than binding off and seaming because you are working stitch by stitch through live loops. For a sweater shoulder with 60 stitches, expect grafting to take 15 to 30 minutes depending on your speed and tension control. The invisible seam is often worth the extra time.

Can I graft in the round?

Grafting is designed for flat pieces with two separate needles. If you are working in the round and want to close a gap, you would normally bind off and seam, or use a kitchener stitch variation designed for circular knitting. Check your pattern for guidance on your specific project.
