A muffler is a tube of fabric you wrap around your neck for warmth

A muffler is a straightforward rectangular piece of fabric sewn into a tube, open at both ends so you can wrap it around your neck. Unlike a scarf, which is a flat rectangle, a muffler is three-dimensional and holds its shape. You can make one by sewing two pieces of fabric together, turning it right-side out, and closing the seam — a project that takes two to four hours depending on your speed and whether you use a machine or hand-sew.

The basic construction is the same whether you sew by hand or machine. You cut two identical rectangles of fabric, place them face-to-face, sew three sides closed, turn the tube inside-out through the opening, press it flat, and stitch the final opening shut. The whole process requires only straight seams, so it is a good first project if you are learning to sew.

Key Takeaways

  • Cut two rectangles of fabric roughly 60 inches long and 10 inches wide, or adjust the length and width to your preference.
  • Pin the two pieces face-to-face, sew three sides with a half-inch seam allowance, and leave one short end open for turning.
  • Turn the tube right-side out through the opening, press it flat with an iron, and hand-stitch the final opening closed with a ladder stitch.
  • A machine-sewn muffler takes about two hours; hand-sewing the entire piece takes three to four hours.
  • Knit fabrics like jersey or fleece are easier to work with than woven fabrics if you are new to sewing.

Measure and cut your fabric pieces

Start by deciding how long you want your muffler. A typical muffler is 55 to 65 inches long and 8 to 12 inches wide, but you can adjust these measurements to your preference. A longer muffler wraps more times around your neck; a wider one covers more of your chest and shoulders. Write down your chosen length and width.

Cut two identical rectangles from your chosen fabric using sharp fabric scissors or a rotary cutter and ruler. Lay the fabric flat on a cutting mat or table, measure carefully, and mark your lines with tailor's chalk or a fabric pencil before cutting. Both pieces must be exactly the same size, or your finished muffler will be lopsided.

Pin and sew three sides of the rectangle

Place the two fabric pieces on top of each other with the right sides (the pretty sides) facing each other and the wrong sides (the back) facing out. Pin around all four edges, leaving the pins about 2 inches apart. This keeps the fabric from shifting while you sew.

Using a half-inch seam allowance, sew three complete sides: both long sides and one short side. Leave the other short side completely open — this is your turning hole. If you are using a machine, sew slowly and keep the edge of the presser foot aligned with the fabric edge to maintain an even seam. If you are hand-sewing, use a running stitch or backstitch, making stitches about one-eighth inch long. Backstitch at the beginning and end of each seam to lock the thread.

Turn the muffler right-side out through the opening

Trim the seam allowance on all three sewn sides to about one-quarter inch, cutting away the extra fabric close to your stitching line. This reduces bulk and helps the muffler lie flat. Clip the corners diagonally, cutting off the corner triangle without cutting into your seam — this prevents the corners from bunching when you turn the tube.

Reach into the opening and grab the fabric from the inside. Gently pull the entire muffler through the hole, turning it inside-out as you go. The right sides of the fabric are now facing outward. Use a point turner or the blunt end of a pencil to push the corners out fully from the inside so they are sharp and square.

Press and close the final seam

Lay the muffler flat on an ironing board and press it with a warm iron, paying special attention to the seams. Press the opening flat as well, folding the raw edges inward by half an inch on both sides and pressing them in place. This creates a clean edge for your final seam.

Close the opening with a ladder stitch, also called an invisible stitch. Thread a needle and knot the end. Bring the needle up through one folded edge, then slide it horizontally inside the fold for about half an inch before bringing it back out. Cross to the opposite folded edge and repeat, sliding the needle inside the fold. Pull the thread gently every few stitches to draw the opening closed. The stitches will be hidden inside the fold. When you reach the end, knot the thread inside the fold and trim.

Hand-sewing the entire muffler

If you do not have access to a sewing machine, you can hand-sew the entire muffler using a backstitch, which is stronger than a running stitch. A backstitch means bringing the needle up through the fabric, then pushing it back down through the previous stitch hole, creating a solid line of thread on the back side. Make stitches about one-eighth inch long and keep them as even as possible.

Hand-sewing three sides of a 60-inch muffler takes roughly two to three hours depending on your speed. The final ladder stitch on the opening takes another 30 to 60 minutes. If you are new to hand-sewing, expect the first muffler to take longer — speed comes with practice. Take breaks to avoid hand fatigue, and do not rush the final seam, as uneven stitches will show on the finished muffler.

Fabric choices that work well for mufflers

Knit fabrics like jersey, fleece, and interlock are the easiest to sew because they do not fray and they stretch slightly, which makes turning and closing the seams simpler. Fleece is especially forgiving because it does not require hemming and holds its shape well. If you are sewing your first muffler, choose fleece or a cotton-blend knit.

Woven fabrics like cotton, linen, and wool require more care because their edges fray. If you choose a woven fabric, trim your seam allowances close to the stitching line and consider finishing the raw edges with a zigzag stitch on a machine or a whip stitch by hand. Avoid slippery fabrics like satin or silk until you have sewn a few mufflers, as they are harder to control and pin.

Frequently Asked Questions

Can I add a lining to my muffler?

Yes. Cut two additional rectangles from a contrasting lining fabric, sew them into a tube the same way, and insert the lining inside the outer muffler before closing the final seam. This creates a reversible muffler. The process takes longer but gives you two colors in one piece.

What if my seams are crooked or uneven?

Crooked seams on a muffler are usually not noticeable once it is wrapped around your neck. If the seams are very uneven or the muffler is lopsided, you can unpick the seam with a seam ripper and re-sew it. This is easier on a machine than by hand, but it is possible either way.

How do I keep the muffler from curling at the edges?

Press the finished muffler with a warm iron and let it cool completely before wearing. If you used a knit fabric, the edges may curl slightly — this is normal and usually stops after a few washes. Fleece does not curl. If curling bothers you, hand-stitch a thin binding tape along the open edges before closing the final seam.

Can I make a muffler from old fabric scraps?

Yes, as long as you have two pieces large enough to cut your rectangles from. You can also piece together smaller scraps by sewing them end-to-end before cutting your final rectangles, though this adds extra seams. Repurposed fabric works just as well as new fabric.

What thread should I use?

Use all-purpose polyester or cotton thread that matches your fabric color. If your fabric is a solid color, match the thread exactly. If your fabric is patterned, choose a thread color that blends with the dominant color. The thread color matters most on the final ladder stitch, which is visible on the outside.
