How to Line a Purse: A Complete Fabric Lining Tutorial with Pockets

There is something deeply satisfying about opening a handmade bag and finding a beautifully finished interior. A well-sewn lining transforms a purse from a simple fabric shell into something that feels polished, professional, and genuinely useful. If you have been putting off adding a lining to your handmade bags because the process seems complicated, this tutorial will walk you through every step — from choosing your fabric to sewing in a functional pocket — so you can finish your next project with confidence.

Whether you are lining a tote bag, a structured handbag, a crossbody, or a simple drawstring pouch, the principles remain largely the same. Once you understand how lining works, you will be able to adapt the technique to almost any bag pattern you make.

Why Lining a Purse Matters

Before we get into the how-to, it is worth understanding why a lining is worth the extra effort. A purse lining serves several practical purposes beyond just looking pretty.

First, it protects the interior seams of your bag. Without a lining, the raw seams inside your bag catch on everything — keys, pens, lipstick — and over time they fray and weaken. A lining covers all of that and gives the bag a much longer life.

Second, it adds structure. Even a lightweight lining fabric gives a bag a little more body and helps it hold its shape when it is sitting on a surface or hanging from your shoulder. If you use a stiffer interfacing behind your lining, you can dramatically change how a bag behaves.

Third, it makes the bag easier to use. A smooth lining means you can easily reach into the bottom of your bag and feel around for what you need. Dark interiors on unlined bags are notorious for swallowing lip balm and coins into their seam allowances.

And finally, pockets. A lining is what makes interior pockets possible. A slip pocket, a zippered pocket, a divided organizer pocket — all of these live on the lining panels, which means you can add as much organization as you like without it showing on the exterior of the bag.

What You Will Need

Gathering your materials before you start saves you from stopping mid-project to hunt for supplies. Here is what you will need for a standard purse lining with at least one interior pocket.

Lining Fabric: You want something that is smooth enough to allow items to slide in and out easily, but sturdy enough to handle daily use. Quilting cotton is a popular choice for beginners because it is widely available, comes in thousands of prints, and is easy to sew. Satin and charmeuse look luxurious but can be slippery and frustrating if you are new to lining construction. Canvas and twill are excellent for structured bags. A medium-weight cotton or cotton-blend is a great all-purpose starting point.

Interfacing: Fusible interfacing is optional but highly recommended, especially if your lining fabric is lightweight or if you want the bag to hold its shape. A woven fusible interfacing gives the best results for a structured bag. Non-woven interfacing is fine for lighter projects.

Thread: Match your thread to your lining fabric. Polyester all-purpose thread works well with most lining fabrics.

Sewing Machine: You do not need anything fancy. A basic machine with a straight stitch and a zipper foot (if you are adding a zippered pocket) is all that is required.

Iron and Ironing Board: Pressing your seams as you go is one of the single most impactful habits you can develop as a sewist. It makes everything fit better and look more professional.

Scissors or Rotary Cutter and Cutting Mat: Sharp cutting tools make a significant difference. Dull scissors cause fraying and inaccuracy.

Ruler or Measuring Tape: Precision matters in bag making more than in some other sewing projects.

Pins or Clips: Sewing clips (like Wonder Clips) are especially useful for bag making because the thick layers can be hard to pin through.

Optional: A hand sewing needle and matching thread for closing the lining by hand, a zipper for a zippered pocket, and ribbon or twill tape for reinforcing strap attachment points.

Choosing the Right Lining Fabric

The lining fabric you choose should complement the exterior fabric in weight and care instructions. If your exterior is a heavy canvas or denim, a quilting cotton or cotton twill lining pairs well. If your exterior is a medium-weight fabric, a lighter lining works beautifully. Avoid using a lining fabric that is significantly heavier than your exterior, as this can cause the bag to feel stiff or pull outward at the seams.

For color and print, you have complete creative freedom. Some makers prefer a lining that blends with or coordinates with the exterior, while others love a bold surprise print inside — a floral exterior with a geometric lining, for instance, or a neutral canvas bag with a bright striped interior. There are no rules here, only preferences.

One practical consideration: if your bag will carry items that might transfer color (think of a damp umbrella, an uncapped marker, or a leaky pen), a darker lining will hide stains better than a pale one.

How to Cut Your Lining Pieces

In most cases, you will cut your lining pieces to the same dimensions as your exterior bag pieces. If your bag pattern comes with a separate lining template, use that. If not, trace or measure your exterior pieces and cut matching pieces from your lining fabric.

There is one important exception: the lining typically needs to be slightly shorter than the exterior if you are dropping the lining into the bag and sewing it to the top edge. The exact amount varies by pattern, but a general guideline is to cut the lining about half an inch shorter than the exterior pieces. This prevents the lining from poking out of the top of the finished bag.

If you are using interfacing, fuse it to the wrong side of your lining pieces now, before you sew anything. Follow the interfacing manufacturer’s instructions for heat settings, and always use a pressing cloth to protect your fabric.

How to Sew a Slip Pocket

A slip pocket is the simplest and most useful pocket you can add to a bag lining. It is essentially a flat pocket sewn onto the lining panel before the lining is assembled. You can make it any size you like, and it is easy to divide it into smaller sections for organizing pens, cards, or a phone.

Step 1: Cut Your Pocket Fabric

Decide how large you want your pocket to be. A good general-purpose size is about 8 inches wide and 6 inches tall, but you can customize this based on your bag size. Cut a piece of lining or coordinating fabric that is twice the height of your desired finished pocket, plus half an inch for seam allowances. So for a 6-inch-tall pocket, you would cut a piece that is 12.5 inches tall by the desired width (plus half an inch on each side for seam allowances).

Step 2: Fold and Press

Fold the pocket piece in half with right sides together so that the short ends meet. Press the fold. Then open it back up. This fold line marks the top edge of your pocket.

Step 3: Sew the Top Edge

With right sides together, sew along the top edge of the pocket using a half-inch seam allowance. Leave a small gap of about 2 inches in the center of that seam so you can turn the pocket right side out. Trim the seam allowance at the corners to reduce bulk, then turn the pocket right side out through that gap. Push the corners out gently with a blunt tool (a knitting needle or a chopstick works perfectly). Press the pocket flat, folding the seam allowance of the gap inward as you press.

Step 4: Position the Pocket on Your Lining

Place your lining panel flat on your work surface, right side facing up. Position the pocket on the lining where you want it, centering it horizontally and placing it at a comfortable height — typically about 2 to 3 inches down from the top edge of the lining panel. Pin or clip the pocket in place.

Step 5: Edgestitch the Pocket

Sew around the sides and bottom of the pocket very close to the edge — about an eighth of an inch from the edge. This is called edgestitching. Backstitch at the beginning and end of your stitching, and add extra backstitching or a small triangle of stitching at the top corners of the pocket for reinforcement. These corners take the most stress, so reinforcing them means your pocket will hold up to years of use.

Step 6: Divide the Pocket (Optional)

If you want to divide the pocket into sections — say, one section for a phone and one for cards — simply sew a vertical line of stitching from the top edge of the pocket to the bottom, at whatever point divides the pocket as you like. Backstitch at both ends.

How to Sew a Zippered Pocket

A zippered pocket adds a secure compartment inside your bag — ideal for valuables like cards, cash, or keys. It takes a little more confidence than a slip pocket, but once you have done it once, it becomes a straightforward process.

You will need a zipper that is slightly shorter than the width of your finished pocket. A 7-inch or 9-inch zipper works well for most bags.

Step 1: Mark the Zipper Opening

On the right side of your lining panel, draw a rectangle where the zipper will go. The rectangle should be the same length as your zipper tape and about half an inch tall. This is your stitching guide.

Step 2: Attach the Zipper Facing

Cut a small rectangle of fabric (about 2 inches taller than the zipper opening rectangle, and the same width) to serve as your pocket facing. Place it right side down on the right side of your lining panel, centered over the marked rectangle. Pin it in place and stitch around the rectangle exactly on your marked lines.

Step 3: Cut the Opening

Using small, sharp scissors, cut through both the lining and the facing fabric down the center of the rectangle, stopping about half an inch from each end and then cutting diagonally into the corners. Be careful not to cut through your stitching. When you open the cut, you should have a clean rectangular opening.

Step 4: Push the Facing Through

Push the facing fabric through the opening to the wrong side of the lining. Press carefully, making sure the corners are clean and square, and that no facing fabric is visible from the right side.

Step 5: Attach the Zipper

Position the closed zipper behind the opening so the zipper teeth are centered and visible through the opening. Tape or pin it in place. Using a zipper foot on your machine, stitch around the opening close to the edge, securing the zipper in place.

Step 6: Attach the Pocket Bag

Cut a rectangle of fabric for the pocket bag, roughly 9 inches by 8 inches (or the size appropriate for your bag). Fold it in half, then sew the facing piece to the top of the pocket bag and stitch the sides and bottom closed. Trim the seam allowances and you have a finished zippered pocket.

Assembling the Lining

Once your pockets are attached to the lining panels, it is time to assemble the lining itself.

Place your lining panels right sides together, matching the edges carefully. Sew the side seams and the bottom seam, using the seam allowance specified in your pattern (usually half an inch to five-eighths of an inch). If your bag has a boxed bottom or gussets, replicate the same shaping in the lining.

Leave an opening of about 4 to 5 inches in one of the seams — the bottom seam is the most common choice. Do not backstitch at the edges of this opening, but do backstitch at the beginning and end of your seams. This opening is how you will turn the whole bag right side out at the end of the construction process, so it needs to be large enough to reach through comfortably.

Press your seams open or to one side, depending on the thickness of your fabric.

Attaching the Lining to the Bag

This is the step where everything comes together. With your exterior bag assembled (but not yet turned right side out) and your lining assembled (right side out), place the lining inside the exterior bag so that the two are right sides together. The exterior of the bag is facing outward; the lining is right side out so that its right side faces the right side of the exterior.

Align the top edges of the lining and exterior, matching the side seams. Pin or clip all the way around. Sew around the top edge of the bag, joining the lining to the exterior. If your bag has handles or straps, they should be tucked down between the lining and exterior layers at this point, with their raw ends pointing upward past the top edge. When you sew the top seam, you will catch those strap ends in the seam, securing them firmly.

Trim the seam allowance at the top edge to reduce bulk, and clip any curves if your bag has a shaped top opening.

Now reach through the opening you left in the lining seam and pull the entire bag through. Push out the corners and edges carefully. Press the top edge of the bag so it lies flat and looks neat.

Fold the seam allowance of the opening in the lining to the inside and press it flat. Sew the opening closed — either by machine, sewing close to the folded edge, or by hand using a ladder stitch for an invisible finish.

Push the lining down inside the exterior bag. If your lining was cut slightly shorter than the exterior, it will settle neatly below the top edge. Press the top edge of the bag one more time, and if you like, topstitch around the opening to keep the lining from shifting and to give the bag a crisp, finished look.

Tips for a Professional Finish

There are a few habits that separate a beautifully finished lining from one that looks homemade in a less-flattering way.

Press at every stage. Every seam, every fold, every pocket. Heat setting your work as you go makes an enormous difference in how the final piece looks.

Grade your seam allowances in thick areas. When multiple layers come together — especially at the top edge where the lining, exterior, straps, and interfacing all meet — trimming each layer to a slightly different width (called grading) reduces bulk and helps the seam lie flat.

Clip your curves and corners. If your bag has any rounded edges or corners, clipping into the seam allowance before turning allows the fabric to spread smoothly instead of puckering.

Use the right needle for the job. If you are sewing through multiple layers of canvas, use a heavier needle (size 90 or 100). For fine cotton, a standard 80/12 works well. A sharp, appropriate needle reduces skipped stitches and fabric damage.

Sew slowly at thick spots. Rather than forcing the machine through a difficult seam, slow down and use your handwheel to take one stitch at a time if needed. This protects your machine and gives you more control.

Test your stitch length. For most bag construction, a slightly longer stitch (3.0 mm to 3.5 mm) looks better and is stronger than a very short stitch.

Common Mistakes and How to Avoid Them

Even experienced sewists run into a few familiar pitfalls with bag lining. Here are the most common ones and how to sidestep them.

Forgetting to leave the turning gap in the lining seam is one of the most common mistakes, and it is a frustrating one to discover at the end of the project. Set a reminder for yourself by marking the gap on your lining panel with tailor’s chalk before you begin sewing.

Cutting the lining too large so it bunches at the top of the bag is another frequent issue. When in doubt, cut the lining half an inch shorter than your exterior panel height. You can always trim a little more if needed.

Skipping the interfacing on a lightweight lining and ending up with a floppy, shapeless bag interior is easy to avoid by simply pressing your interfacing on before you cut. It adds only a few minutes and makes a significant difference.

Sewing the straps or handles in the wrong direction so they twist when the bag is turned right side out can be caught by double-checking before you sew the final top seam. Fold the handles down into the bag carefully, check that they are oriented correctly, then clip and sew.

Adapting This Tutorial to Different Bag Styles

The approach described here works for the majority of common bag styles, but there are a few adaptations worth knowing.

For a drawstring bag, the lining is inserted into the exterior and the top is finished with a casing for the drawstring cord. The lining is usually basted to the exterior at the top before the casing is applied.

For a structured box bag or frame bag, you may need to pad or stiffen the lining panels with foam or stiff interfacing before assembly, and the attachment method may differ based on the frame or hardware being used
