A necktie is sewn in layers, starting with two fabric pieces cut on the bias and joined at the center seam, then folded and stitched to create the diagonal grain that gives a tie its drape

The basic construction involves cutting two identical pieces from your fabric, sewing them together inside-out along three sides, turning the whole thing right-side-out, then hand-stitching the opening closed. The bias cut — cutting the fabric at a 45-degree angle to the grain — is what makes a tie hang properly instead of twisting or curling. Most ties are lined with a strip of interfacing or a separate backing fabric to add weight and help them hold their shape.

The finished tie is typically 3 to 3.5 inches wide at the widest point and 52 to 60 inches long, though you can adjust both measurements to your preference. The whole process takes three to five hours for a beginner, mostly because hand-stitching the final seam is slow work. You will need a sewing machine for the main seams, a needle and thread for closing the opening, and fabric scissors or a rotary cutter.

Key Takeaways

  • Cut your fabric pieces on the bias (45-degree angle to the grain) so the tie will drape and hang straight instead of twisting.
  • Sew the two fabric pieces together inside-out on three sides, leaving one short end open for turning and stuffing the interfacing.
  • Turn the tie right-side-out through the opening, press it flat, then hand-stitch the opening closed with a ladder stitch or whip stitch.
  • A basic tie needs only two fabric pieces and thread; adding interfacing or a backing strip makes it hold its shape better and last longer.
  • Most ties are 52 to 60 inches long and 3 to 3.5 inches wide at the widest point, but you can adjust these to fit your frame or preference.

Cutting the fabric on the bias

The bias cut is the single most important step in tie-making. Fabric has a grain — the direction the threads run — and cutting at a 45-degree angle to that grain gives the tie flexibility and allows it to hang without twisting. If you cut a tie on the straight grain instead, it will curl and fold awkwardly no matter how well you sew it.

To find the bias, fold one corner of your fabric so the edge aligns with the selvage (the finished edge). The fold line is the bias. Mark a line parallel to this fold across your fabric using tailor's chalk or a fabric pencil. Cut two identical rectangles along this line. For a standard tie, each piece should be roughly 4 inches wide and 60 inches long, though the exact size depends on how wide you want the finished tie and how much seam allowance you plan to use.

Use a rotary cutter and ruler if you have them — they are faster and more accurate than scissors. If you are cutting by hand, a pair of sharp fabric scissors works fine, but dull scissors will fray the edges and make sewing harder. Take your time with this step; a crooked cut will throw off the whole tie.

Sewing the two pieces together

Place the two fabric rectangles with the right sides facing each other (the pretty sides touching). Pin them together along the long edges and one short end, leaving the other short end unpinned. This unpinned end is where you will turn the tie right-side-out later.

Sew along the three pinned sides using a 1/4-inch seam allowance and a straight stitch. Start at one corner of the long edge, sew down the length, around the short end, and back up the other long edge. Backstitch at the beginning and end to lock the thread. Remove the pins as you go. When you reach the unpinned short end, leave it open — do not sew across it.

Trim the seam allowance at the corners diagonally, cutting away the excess fabric close to (but not into) the stitching. This reduces bulk when you turn the tie right-side-out and helps the corners lie flat. Clip the seam allowance along the long edges every inch or so, cutting perpendicular to the seam. These clips allow the fabric to spread smoothly when turned.

Turning and pressing the tie

Turn the tie right-side-out through the open short end by reaching in and pulling the fabric through. Start by pushing one long corner through, then work the rest of the fabric out gradually. This takes patience — go slowly to avoid tearing the seams. Once the tie is fully turned, use a point turner or the blunt end of a chopstick to push the corners out so they are sharp and square.

Press the tie flat with an iron on a low to medium heat setting. Lay it on an ironing board with the seam running down the center back, and press from the back side first, then the front. The seam should sit exactly in the middle of the back of the tie. If it is off-center, gently work it into place before pressing again. A well-pressed tie will hold its shape much better when worn.

Adding interfacing or a backing strip

At this point you have a hollow tie. You can leave it hollow, but most ties are lined or backed with a strip of material that adds weight, helps the tie hold its shape, and prevents it from twisting. The two common options are a strip of interfacing (a stiff fabric used in garment-making) or a separate backing fabric sewn to the inside.

If using interfacing, cut a strip about 1.5 inches wide and as long as the tie. Slide it inside the tie through the open end and center it so it runs down the middle. If using a backing fabric, cut a rectangle the same length as the tie and about 2 inches wide, fold the long edges inward by 1/4 inch, press, then slide it inside the tie and pin it in place before hand-stitching it down.

Either way, the backing or interfacing should not extend all the way to the open end — leave about 2 inches of space at the opening so you have room to hand-stitch the final seam without sewing over the backing.

Hand-stitching the opening closed

Thread a hand-sewing needle with thread that matches your tie fabric. The ladder stitch (also called an invisible stitch or whip stitch) is the standard choice because the stitches are hidden inside the fold of the fabric. Fold the raw edges of the opening inward by 1/4 inch on both sides and press them flat with your fingers or a quick touch of the iron.

Bring the needle up through one folded edge, then across to the opposite folded edge and through the fold. Slide the needle inside the fold for about 1/4 inch, then bring it back out and across to the first side. Repeat this back-and-forth motion, keeping your stitches small and tight. Every few stitches, gently pull the thread to close the opening. The stitches should be nearly invisible from the outside.

When you reach the end of the opening, tie off the thread by making a small loop, passing the needle through it, and pulling tight. Trim the thread close to the fabric. Press the finished seam one more time with the iron to set it.

Finishing touches and tying the knot

The tie is now complete and ready to wear. If you want to add a loop on the back (the small fabric loop that holds the narrow end in place), cut a strip of fabric about 1.5 inches long and 1 inch wide, fold it in half lengthwise, sew the long edge closed, turn it right-side-out, then hand-stitch it to the back seam about 8 inches from the wide end. Slide the narrow end of the tie through this loop when wearing.

To tie the necktie, drape it around your neck with the wide end on your right side, hanging about 12 inches lower than the narrow end. Cross the wide end over the narrow end, wrap it around behind, bring it back across the front, then pull it up through the loop around your neck and down through the knot you have created. Tighten and adjust until the wide end reaches your belt buckle.

Frequently Asked Questions

What fabric should I use to make a necktie?

Cotton, silk, wool, or linen all work well. Silk is traditional and drapes beautifully but is more expensive and slippery to sew. Cotton and cotton blends are easier to work with and less costly. Avoid stretchy fabrics like jersey or knits — they do not hold their shape well in a tie.

Can I make a tie without a sewing machine?

Yes, but it takes much longer. You can hand-sew the main seams using a backstitch, though the seams will be less even and take two to three times as long. Most people use a machine for the three main seams and hand-sew only the final opening, which is the slowest part anyway.

How do I prevent the tie from twisting after I wear it?

The bias cut and the backing or interfacing both help. Make sure you cut on the true bias (45 degrees to the grain) and add a strip of interfacing or backing fabric down the center. Press the tie flat before wearing it, and hang it on a tie rack or roll it loosely after wearing to help it keep its shape.

What is the difference between a wide tie and a narrow tie?

The width at the widest point. A standard tie is 3 to 3.5 inches wide. A narrow tie (sometimes called a skinny tie) is 2 to 2.5 inches wide. A wide tie is 3.5 to 4 inches wide. Adjust your initial fabric width to match the finished width you want, keeping in mind that you will lose about 1/2 inch total to seam allowances.

Do I need to line the tie with a separate backing fabric, or is interfacing enough?

Interfacing alone is fine for a casual tie. A separate backing fabric adds more weight and structure, which is why formal ties often have it. For your first tie, interfacing is simpler and faster — you can always add a backing fabric on your next one if you prefer the feel and drape.
