A patch pocket is sewn flat to the outside of fabric, not inserted into a seam
A patch pocket is a pocket piece cut from fabric and stitched directly onto the surface of a garment or bag. Unlike an inseam pocket that hides inside a seam, a patch pocket sits visibly on top and becomes part of the design. You sew around three or four edges of the pocket to attach it permanently.
The basic process takes about 15 to 30 minutes per pocket, depending on pocket size and your sewing speed. You will need a sewing machine (or needle and thread for hand sewing), thread that matches your fabric, pins, scissors, and the pocket piece itself. The pocket is usually cut from the same fabric as the garment, though contrast fabric is also common.
Key Takeaways
- Press the pocket edges flat and fold down the top opening edge before pinning to prevent fraying and may support clean lines.
- Pin the pocket in place on the garment, checking that it sits straight and at the depth you want, then sew around three sides using a straight stitch.
- Backstitch at the start and end of each seam to lock the thread and prevent the pocket from coming loose.
- Reinforce the top corners of the pocket with a small triangle or box stitch to handle the stress where hands reach in and out.
Prepare the pocket piece before pinning
Start by cutting your pocket to the finished size you want, plus a seam allowance on all sides—usually 1/2 inch is standard. If your fabric frays easily (cotton, linen, or lightweight blends), press the raw edges under by 1/2 inch on all four sides using an iron. This fold keeps threads from coming loose and gives the pocket a clean, professional edge.
Pay special attention to the top opening edge of the pocket. Fold this edge down by 1/2 inch and press it flat, then fold it down again by another 1/2 inch and press. This double fold creates a finished edge at the opening and prevents the pocket from unraveling when it is used. Pin this folded edge to hold it in place while you work.
If your fabric does not fray much (canvas, heavy cotton, or felt), you can skip the edge pressing on the three sides that will be sewn down, but still press the top opening edge twice. The top edge takes the most wear and needs the strongest finish.
Pin the pocket straight and at the right depth
Decide where the pocket should sit on your garment. For a shirt or jacket, a patch pocket usually sits 2 to 3 inches below the shoulder seam and 1 to 2 inches in from the side seam. For pants or a skirt, it typically sits on the hip, roughly 4 to 6 inches below the waistband. Mark these positions lightly with a fabric pencil or chalk if you are sewing multiple pockets and want them level.
Place the pocket on the garment and pin it at all four corners, then add pins along each edge every 2 to 3 inches. Check that the pocket sits straight by looking at it from the front and from the side. If the top edge is not parallel to the ground (or to the waistband), adjust the pins until it is. Crooked pockets are visible and hard to fix after sewing.
Make sure the pocket opening faces the direction you want—usually upward so you can reach into it. If you are sewing a pocket on a curved surface like a pant leg, pin it gently so the fabric underneath does not bunch or wrinkle.
Sew the pocket down with a straight stitch
Thread your sewing machine with thread that matches your fabric. Set the machine to a straight stitch with a stitch length of 2.0 to 2.5 mm—small enough to hold securely but not so small that the thread breaks easily. If you are hand sewing, use a running stitch or backstitch, making stitches about 1/8 inch apart.
Start at the top left corner of the pocket. Backstitch two or three times to lock the thread, then sew down the left side of the pocket, keeping the needle about 1/4 inch from the edge. When you reach the bottom left corner, backstitch again, then pivot the needle and sew across the bottom. Backstitch at the bottom right corner, then sew up the right side. Stop at the top right corner and backstitch to finish.
Do not sew the top edge of the pocket—that is the opening where your hand goes in. Sewing only three sides (left, bottom, right) leaves the top open and usable. If you accidentally sew the top closed, you will have to cut it open and finish the raw edges, which is extra work.
Reinforce the top corners to prevent tearing
The top corners of a patch pocket take the most stress because hands reach in and out repeatedly. Reinforce these corners by sewing a small triangle or box at each top corner. Start at the top left corner where the left seam meets the top edge. Sew a small triangle by stitching diagonally down and to the right about 1/2 inch, then back up to the corner. Repeat at the top right corner.
Alternatively, sew a small rectangle (about 1/2 inch by 1/4 inch) at each top corner, going over it twice for extra strength. This reinforcement keeps the pocket from tearing open at the corners when it is used hard or washed repeatedly. It also looks intentional and adds a subtle design detail.
Trim threads and press the finished pocket
After sewing, trim all thread tails close to the fabric. If you used a backstitch or running stitch by hand, weave the thread end through a few stitches on the back side before trimming so it does not come loose. Use an iron to press the finished pocket flat against the garment, which helps the seams sit neatly and makes the pocket look polished.
If the pocket fabric puckered or wrinkled while you were sewing, a light press with steam will smooth it out. Be gentle around the seams so you do not flatten them completely—you want them to look crisp, not flattened.
Frequently Asked Questions
Can I sew a patch pocket by hand instead of with a machine?
Yes. Use a backstitch or running stitch with thread that matches your fabric, making stitches about 1/8 inch apart. Backstitch at the start and end of each seam to lock the thread. Hand sewing takes longer but gives you more control and works well for small pockets or delicate fabrics.
What if my pocket fabric is slippery or stretchy?
Use a stabilizer—a thin, temporary fabric you pin or iron to the back of the pocket before sewing. Tear-away stabilizer is easiest: sew through it, then tear it away after you finish. This keeps stretchy knits and slippery fabrics from shifting while you sew.
How do I fix a pocket that is sewn crooked?
If the pocket is only slightly off, you can live with it. If it is noticeably crooked, you will need to remove the stitches with a seam ripper, reposition the pocket, and sew it again. Carefully cut the thread every few stitches and pull them out, then press the holes flat with an iron before resewing.
Should I sew the pocket opening closed after I sew the three sides?
No. The top edge stays open so you can use the pocket. If you want to prevent things from falling out, you can sew a button or snap at the top, but the opening itself should remain unsewn.
Can I sew a patch pocket on stretchy fabric like a t-shirt?
Yes, but use a stabilizer on the back to prevent puckering. You can also use a ballpoint needle and a slight zigzag stitch instead of a straight stitch, which gives the seam a little give when the fabric stretches.
