The basic steps for sewing a pocket
A pocket is a fabric pouch sewn into a seam or onto the surface of a garment. The simplest approach is to cut two matching pieces of fabric, pin them together, sew three sides closed, turn it right-side out, and then stitch the opening shut. The harder part is positioning it correctly on your garment before you attach it—measure twice, pin carefully, and sew slowly so the edges stay even.
Most home sewers start with a patch pocket, which sits flat on top of the garment and is visible from the outside. This is forgiving because you can see exactly where you are sewing and adjust as you go. Once you master that, you can move to inseam pockets, which are hidden inside a seam and require more planning but look more polished.
Key Takeaways
- A patch pocket is the easiest type to sew because it sits on top of the garment and you can see the whole process.
- You need two matching fabric pieces, a needle or sewing machine, thread, pins, and scissors—no special tools required.
- Measure and mark the pocket location on your garment before you pin anything, using a ruler and fabric pencil or chalk.
- Sew slowly along the edges so the seams stay straight and the pocket sits flat against the garment.
- Backstitch at the start and end of every seam to lock the thread and prevent the pocket from coming loose.
What you need to sew a pocket
You need fabric for the pocket itself—usually two pieces cut to the same size and shape. If you are sewing a pocket onto an existing garment, use fabric that matches the garment or complements it intentionally. Scrap fabric works fine for practice.
For tools, you need a needle (hand sewing) or a sewing machine, thread that matches your fabric, pins, scissors, a ruler or measuring tape, and a fabric pencil or chalk to mark where the pocket goes. A seam ripper is useful if you make a mistake, but not essential. If you are sewing by hand, a thimble protects your finger from the needle.
How to cut and prepare pocket pieces
Decide on the finished size of your pocket—a typical shirt pocket is about 4 inches wide and 5 inches tall. Add a half-inch seam allowance on all sides, so cut your two fabric pieces 5 inches wide by 6 inches tall. Use a ruler to draw the outline on your fabric with a fabric pencil, then cut along the line with sharp scissors.
If your fabric frays easily (cotton, linen), you can finish the raw edges with a zigzag stitch on a sewing machine before you assemble the pocket. This is optional but makes the pocket look more finished inside. Place the two pieces with the right sides (the pretty sides) facing each other, and pin around three sides, leaving one short end open.
Sewing the pocket pieces together
Thread your needle or load your sewing machine. If sewing by hand, tie a knot at the end of your thread. If using a machine, set it to a straight stitch with a medium stitch length (about 2.5 on most machines).
Sew along the three pinned sides, staying a half-inch from the edge. Backstitch at the beginning and end—on a machine, press the reverse button for a few stitches; by hand, sew backward over the first few stitches. Leave the fourth side completely open. Remove the pins as you go.
Once you have sewn three sides, trim the corners diagonally, cutting close to (but not through) the stitching. This reduces bulk when you turn the pocket right-side out. Turn the pocket through the open end, pushing the corners out gently with a blunt tool like a chopstick or the back of a spoon. Press the pocket flat with an iron on low heat.
Positioning the pocket on your garment
Measure where you want the pocket to sit. On a shirt, a chest pocket usually sits about 3 to 4 inches below the shoulder seam and centered on the chest. Mark the top-left corner of the pocket location with a fabric pencil or pin. Use a ruler to draw a light rectangle showing where the pocket edges will be.
Pin the pocket to the garment, starting at the corners and working toward the center. Make sure it sits flat and straight—step back and look at it before you sew. If it looks crooked, unpin and reposition. Pinning takes longer than sewing, but it prevents mistakes.
Sewing the pocket to the garment
Sew the pocket to the garment along three sides, leaving the top open. Start at the top-left corner, backstitch, and sew down the left side. At the bottom corner, backstitch, pivot the fabric, and sew across the bottom. At the bottom-right corner, backstitch, pivot, and sew up the right side. Stop at the top-right corner and backstitch.
Sew slowly so you can keep the stitches straight and parallel to the pocket edge. If using a sewing machine, lower the presser foot before you start and raise it before you remove the fabric. If sewing by hand, use small, even stitches about an eighth of an inch apart.
For extra strength, sew the top edge of the pocket as well, or sew a small rectangle or X shape across the top corners. This reinforces the stress points where the pocket gets pulled. Remove all pins and trim any loose threads.
Common mistakes and how to avoid them
The most common mistake is sewing the pocket crooked. Prevent this by measuring twice and pinning carefully before you sew a single stitch. If the pocket ends up crooked, use a seam ripper to cut and remove the stitches, reposition the pocket, and sew again.
Another mistake is leaving gaps at the corners where the pocket opening shows. When you sew the pocket closed, make sure your stitches go all the way into the corners. If you see a gap, sew over that spot again.
Puckering—where the fabric bunches up—usually means you are pulling the fabric too tight as you sew. Let the needle and thread do the work; guide the fabric gently without forcing it. If you are using a sewing machine, do not pull the fabric backward or forward.
Frequently Asked Questions
Can I sew a pocket by hand, or do I need a sewing machine?
You can sew a pocket entirely by hand. It takes longer—maybe 20 to 30 minutes instead of 5 to 10 minutes on a machine—but the result is just as strong if your stitches are small and even. Use a needle that fits comfortably in your hand and thread that matches your fabric.
What if I want a pocket with a flap on top?
Sew the pocket the same way, but before you attach it to the garment, sew a separate flap piece (two rectangles of fabric sewn together and turned right-side out). Pin the flap to the top edge of the pocket, then attach the whole assembly to the garment. The flap covers the pocket opening.
How do I sew a pocket into a seam instead of on top?
An inseam pocket requires planning before you cut your garment pieces. The pocket is sandwiched between two layers of the garment fabric along a seam line. This is more advanced—start with patch pockets first, then look for a pattern that includes inseam pockets once you are comfortable with basic sewing.
What thread color should I use?
Use thread that matches your garment fabric as closely as possible. If you cannot find an exact match, choose a shade slightly darker than the fabric. The stitches will be less visible. If the pocket is a contrasting color on purpose, you can use thread that matches the pocket instead.
Can I wash a garment with a hand-sewn pocket?
Yes. Hand-sewn pockets are just as durable as machine-sewn ones if the stitches are small and tight. Wash the garment in cool water and lay it flat to dry, or follow the care instructions for the fabric. The pocket will not come loose from normal washing and wearing.
