How to Make a T-shirt? | Sew It Yourself From Scratch

Making your own T-shirt starts with either sewing fabric or printing a design onto a blank. For home sewists, the standard method produces a durable, custom-fitting shirt using a front, back, two sleeves, and a neckband. The process works with cotton, polyester, or cotton-polyester blends and uses a sewing machine set to a stretch or zigzag stitch.

If you would rather buy a finished tee and customize it with a design, we also cover the iron-on transfer method later in this guide. For the ready-to-wear option, see our roundup of the best ever T-shirt picks.

What You Need to Sew a T-Shirt

Gather a T-shirt pattern (or trace one from a well-fitting shirt), about one yard of knit fabric, coordinating thread, and a sewing machine capable of a stretch or zigzag stitch. Common fabric choices are 100% cotton, polyester, or a cotton-polyester blend. Prewash or steam the fabric to prevent post-sewing shrinkage.

The four main pattern pieces are: front (cut on the fold), back (cut on the fold), two sleeves, and a neckband. Add seam allowance if your pattern does not include it — skipping this step is a common reason the finished shirt runs small.

How to Sew a T-Shirt: Step-by-Step

The construction order that many tutorials follow is: shoulders first, then neckband, then sleeves, then side seams, then hems. Each step uses a stretch-compatible stitch to keep the seams flexible and durable.

1. Prepare the fabric and pattern. If tracing from an existing shirt, lay it flat, trace around the body, and adjust the neckline as needed. Add seam allowance before cutting. Cut the front, back, sleeves, and neckband pieces aligned to the grain.

2. Sew the shoulder seams. Place the front and back right sides together. Stitch across each shoulder with a stretch stitch. Press the seams open or toward the back.

3. Attach the neckband. Fold the neckband strip lengthwise and pin it to the neckline, matching key points like the shoulder seams and center front. Sew in place using a zigzag or stretch stitch. Pin carefully — poor pinning can distort the neckline.

4. Insert the sleeves. Match the sleeve cap to the armhole, pinning at the shoulder point and any notches. Stitch through all layers with a stretch stitch. Repeat for the second sleeve.

5. Sew the side seams. With right sides together, stitch from the underarm down to the hem in one pass. This seam closes both the body and the sleeve in a single line.

6. Hem the sleeves and bottom. Fold the fabric under roughly ½ to 1 inch and stitch. Use a twin needle or a zigzag stitch for a professional finish that stretches with the fabric.

How to Print a Custom Design at Home

If you prefer to customize a blank T-shirt, the iron-on transfer method works for home use. Lay the shirt flat on an ironing board and preheat your iron to maximum heat without steam. Follow the transfer paper manufacturer’s instructions for light-fabric or dark-fabric paper — the orientation required differs by type.

Place the transfer in the correct position, apply firm even pressure for the recommended duration (often 30 to 60 seconds), then peel carefully. For extra durability, press the design again from the inside out. This method applies to standard blank shirts and does not involve sewing or pattern pieces.
