The Basic Process: Hand-Stitching the Lining to Your Jacket
A jacket lining is sewn in by hand after the jacket body is complete. You slip the finished lining inside the jacket (wrong sides facing each other), pin it in place at the seams and armholes, then use a slip stitch to close the opening where the lining meets the jacket fabric. The slip stitch is nearly invisible because the thread runs inside the fold of fabric rather than across the surface. This method takes 45 minutes to two hours depending on jacket size, and it is the standard approach for tailored jackets because it gives a clean, professional finish.
The lining should already be sewn into a tube before you begin—the front pieces, back piece, and sleeves are stitched together, but the bottom opening and armholes are left open. Your jacket body should also be complete, with sleeves attached and all seams pressed. The lining goes in last, after you have finished everything else.
Key Takeaways
- The lining is inserted after the jacket is fully assembled, with the lining tube turned inside out and slipped into the jacket wrong-side-to-wrong-side.
- You pin the lining to the jacket at the shoulder seams, armholes, and neckline before stitching, so it does not shift while you work.
- A slip stitch sewn by hand closes the opening at the bottom of the jacket, with the needle running inside the fold of fabric so the thread stays hidden.
- The armhole seam allowances are catch-stitched (a loose, flexible stitch) rather than slip-stitched, because this area needs to move with your arm.
Preparing the Lining and Jacket Before You Start
Press both the lining and the jacket body with an iron before you begin. The lining should be a finished tube with the front pieces, back, and sleeves all sewn together. Leave the bottom opening (where the lining will eventually close) and the armholes open. The jacket should have all seams pressed, sleeves attached, and the neckline finished (either with bias tape or a facing).
Turn the lining inside out—so the wrong side of the lining fabric faces outward—and slip it into the jacket. The wrong sides of both the lining and jacket should now be facing each other. This is the opposite of how you would normally put two pieces together. Smooth the lining so it sits evenly inside the jacket and does not bunch at the shoulders or sides.
Pinning the Lining at the Seams and Armholes
Start by pinning the lining to the jacket at the shoulder seams. Push a pin through both layers at the point where the shoulder seam of the lining meets the shoulder seam of the jacket. Do the same at the side seams where the lining and jacket seams align. These pins anchor the lining so it cannot slip while you stitch.
Next, pin around the armholes. The lining armhole seam should sit just inside the jacket armhole seam. Pin every 2 to 3 inches around each armhole. The lining should lie flat against the jacket—if you see wrinkles or puckers, unpin that section, smooth it out, and repin. At the neckline, pin the lining to the neckline facing or bias tape, again spacing pins every 2 to 3 inches.
Slip-Stitching the Bottom Opening Closed
The bottom of the jacket is where the lining and jacket meet and close. Fold the raw edge of the lining under by about half an inch and press it with your fingers or an iron. Do the same with the raw edge of the jacket hem. Pin these folded edges together so they meet edge-to-edge.
Thread a needle with thread that matches the lining fabric. Knot the end. Bring the needle up through the fold of the jacket hem from the inside, so the knot sits hidden in the fold. Slide the needle along inside the fold of the jacket for about a quarter inch, then push it straight out through the fold of the lining. Slide the needle along inside the lining fold for a quarter inch, then push it back out through the jacket fold. Repeat this motion all the way around the bottom opening. The thread should run inside the folds and be nearly invisible from the outside. Pull the thread snug every few stitches, but not so tight that the fabric puckers.
When you reach the end, make a small knot inside one of the folds and trim the thread. The opening should now be closed with a seam that is barely visible.
Catch-Stitching the Armholes and Neckline
The armholes and neckline need a different stitch than the bottom opening because these areas must stretch slightly when you move your arm. Use a catch stitch instead of a slip stitch. A catch stitch is looser and more flexible—it allows the fabric to give a little without the thread breaking.
Bring the needle up through the fold of the lining, then take a tiny stitch (just two or three threads) in the jacket seam allowance. Bring the needle back out and slide it along inside the lining fold for about a quarter inch before taking another tiny stitch in the jacket. The stitches should be small and loose, with visible gaps between them. This slack in the thread allows the armhole to move. Work your way around both armholes and the entire neckline, keeping the stitches small and the tension loose.
Finishing Touches and Common Mistakes to Avoid
Once the lining is stitched in place, remove all the pins. Press the jacket lightly with an iron on a low setting, using a pressing cloth between the iron and the fabric to avoid shine. Do not press hard—you just want to set the stitches and smooth any wrinkles.
The most common mistake is pulling the thread too tight, which causes the fabric to pucker and makes the stitches visible. Keep your tension loose and even. Another mistake is not pinning enough before you stitch, which causes the lining to shift and bunch. Pin every 2 to 3 inches and check that the lining lies flat before you begin stitching. If you are using a slip stitch and the thread keeps showing on the outside of the jacket, you are not running the needle far enough inside the fold—aim for at least a quarter inch inside the fold before you push the needle back out.
Frequently Asked Questions
Can I use a sewing machine to attach the lining instead of hand-stitching?
You can machine-stitch the armholes and neckline with a stretch stitch or narrow zigzag, but the bottom opening should be hand-stitched with a slip stitch. Machine stitching at the bottom creates a visible seam line that looks less professional. Hand stitching takes longer but gives a tailored finish that is worth the time.
What if the lining is too long or too short for the jacket?
The lining should be about half an inch shorter than the jacket hem so it does not show at the bottom. If it is too long, trim the excess before you fold and pin the bottom edge. If it is too short, you may have cut it incorrectly—check your pattern. For future jackets, measure the finished jacket length before you cut the lining pieces.
How do I fix a lining that is bunching at the shoulders?
Unpin the shoulder area and smooth the lining out again, working from the neckline down toward the armholes. The lining should lie flat without wrinkles. Repin and check before you stitch. If bunching happens after you have already stitched, you can carefully cut the stitches with a seam ripper, smooth the lining, and re-stitch.
Do I need to attach the lining at the sleeve hems?
Yes. Fold the raw edge of the lining sleeve under by half an inch and slip-stitch it to the inside of the jacket sleeve hem, using the same technique as the bottom opening. This keeps the lining from sliding up into the sleeve when you wear the jacket.
