How to Sew a Wallet
This bifold wallet has six card slots, a bill pocket, and a lined outer. It is a small project with a lot of folding, so accuracy matters more than speed.

- 1/3 yard (30 cm) lining fabric
- Medium fusible interfacing
- Polyester thread
- One small snap or a length of hook and loop tape
Tools
- Sewing machine
- Walking foot (optional)
- Iron and pressing mat
- Fabric clips
- Point turner or chopstick
Steps
- 01
Cut and interface everything
Cut two outer panels 8 x 4.5 inches (20 x 11 cm) and two lining panels the same size. Cut six card slot pieces 8 x 3 inches (20 x 7.5 cm) and one bill pocket 8 x 4 inches (20 x 10 cm). Fuse medium interfacing to the outer panels and the bill pocket.

Fold the card slots
Press each slot piece in half lengthwise, wrong sides together, so it measures 8 x 1.5 inches (20 x 3.75 cm). Topstitch 1/8 inch (3 mm) from the folded edge on all six pieces to hold the layers flat while you stack them.
- 03
Stack the card slots
Lay three slot pieces on one lining panel, overlapping them so each sits 3/4 inch (2 cm) above the one below. Pin the stack in place and baste around the sides and bottom, then repeat with the other three slots on the second lining panel.

Add the bill pocket
Center the bill pocket on the right side of one outer panel with the bottom edges aligned. Sew around the sides and bottom with a 1/4 inch (6 mm) seam, then fold the pocket up and topstitch its top edge to the panel.
- 05
Join the layers
Place one lining panel right side up, then the bill pocket outer panel right side down on top, then the second outer panel, then the second lining panel. Sew all the way around with a 3/8 inch (1 cm) seam, leaving a 3 inch (8 cm) gap in one short end.
- 06
Turn, press, and topstitch
Clip the corners, turn the wallet through the gap, and push the corners out with a point turner. Press firmly, slip stitch the gap closed, and topstitch 1/8 inch (3 mm) around the outer edge. Fold the wallet in half and press the fold.
Why the folded card slot does the real work
Each slot starts as an 8 x 3 inch (20 x 7.5 cm) strip pressed in half, and that single fold carries three jobs at once. It buries the raw edge at the mouth of the pocket, it doubles the cloth exactly where a card drags in and out, and it gives the slot a straight top edge that stays parallel to the panel underneath it. A slot left with a raw top edge starts to curl and fray at the opening within a few weeks of daily use.
The 1/8 inch (3 mm) topstitch along the folded edge is not decoration. It laminates the two layers into one so the fold cannot roll open, and it stops the layers separating when a card is pushed in. Sew it before you stack: once three slots are overlapped, the lower ones sit under the presser foot and feed unevenly.
The 3/4 inch (2 cm) offset is what sets the finished proportions. Folded, a slot is 1.5 inches (3.75 cm) deep, so laying the next slot 3/4 inch above it leaves half of that slot visible and half covered. Change the offset and you change both how much card edge shows and how tall the whole stack becomes; a wider offset makes a taller stack that crowds the bill pocket and thickens the side seams you have to sew through later.
Baste each stack to its lining panel so the stitching lands inside the final 3/8 inch (1 cm) seam allowance. That way the basting is buried permanently, and it also holds the layers steady while the outer seam is sewn. Because all six slots are anchored to the lining rather than the outer panel, the card stack pulls on the lining every time the wallet is opened, which is why the lining needs to be a tight weave rather than something loose.
Mistakes you can see in the finished wallet
Drifting slots are the most common problem, and they come from measuring each new slot against the piece above it instead of against the panel. A 1/8 inch error repeated twice leaves the top slot visibly taller than the rest. Mark all three placement lines on the lining with a ruler and a removable marker before pinning anything, and after basting, check that the side edges of the stack are flush with the lining so the final seam follows one flat edge rather than a staircase.
A hard, polished crease along the slot fold is a weak point, not a crisp finish. Fabric cracks along a crease that has been pressed flat under a sliding iron, so use steam and an up-and-down pressing motion instead of gliding. The same applies to the interfaced outer panels: once the fusible is applied, let the panel cool completely flat before you move it, or the interfacing will bubble and show through the finished outer.
Blunt, lumpy corners mean the corners were clipped into the stitching. Cut across each corner but stop a thread's width short of the seam line, and after turning, push the corner out from the inside with the point turner against the seam rather than against the fabric. Pushing the cloth itself stretches the point out of shape and it never presses back square.
The side seams are where the machine will complain, because each one crosses the card stack plus two outer panels and two linings. If it stalls, do not push or pull the fabric: lengthen the stitch slightly and turn the handwheel through the thickest stretch. Mark both ends of the 3 inch (8 cm) gap with pins before you start sewing so you backstitch in the right places; a gap that creeps wider while you clip the corners is the usual reason one end of a finished wallet looks lumpy.
Fabric, interfacing, and closure: what a substitution changes
The outer fabric supplies the wallet's body. Cotton canvas, as listed, holds its shape with just medium interfacing. Swap in a quilting cotton and you need to go up to a heavier interfacing or the wallet slumps in the hand and the bill pocket sags forward. Go the other way, to a heavy canvas or a light denim, and you can use less interfacing, but the extra bulk makes the wallet harder to turn through the gap and gives a thick ridge at the fold.
Whatever touches the cards should be smooth and tightly woven, which is why the lining matters as much as the outer. Poplin or a firm quilting cotton lets cards slide; brushed cotton or flannel grips them, so they come out slowly and every seam gets thicker. Cutting the six slot pieces from the lining cloth instead of the outer keeps the stack slightly thinner, which helps if your machine is already struggling at the side seams.
Medium fusible on the outer panels and the bill pocket is the balance point in this project. Fuse with the iron held still for the full fusing time, then let the piece cool completely flat, because peeling up a warm fuse is exactly how ripples appear through a finished outer panel. Lighter interfacing makes the top of the bill pocket floppy right where a folded bill presses against it; heavier interfacing makes the topstitching on that pocket edge harder to keep straight.
For the closure, a sew-on snap needs a small square of fusible behind each half or the fabric around the snap will tear out with use. Hook-and-loop tape is bulkier and collects lint, but it needs no setting tool and lets you shift the closed position slightly. Either way, fold the finished wallet first and mark where the two panels actually meet: sewing the layers pulls the fold off center, so a snap set from paper measurements alone often lands crooked.
Variations for a different look or an easier build
A contrast interior is the cheapest change with the biggest effect. The six slots are the largest single area you see when the wallet opens, so cut them from a print or a bright solid and keep the outer plain; the cut size stays 8 x 3 inches (20 x 7.5 cm) and only the fabric changes. Pick a slot fabric close in weight to the outer, or the stack will sit unevenly under the topstitching.
For a first build, drop the bill pocket and make a card case. The join and the 3/8 inch (1 cm) seam are identical, but you lose a whole layer from one side, so the wallet turns easily and presses flat in seconds. The same reasoning applies if you cut the slot count from six to three: a single stack of three slots at the 3/4 inch offset is a much flatter sandwich, and the side seams stop fighting the machine.
An ID window is a small addition with its own rules. Cut the window from the top slot before folding and back it with clear vinyl: vinyl has no grain and does not fray, so it needs no folded edge, but it cannot take a hot iron and it grips the presser foot. Lay a strip of tissue over it while you topstitch and tear the tissue away afterward. Put the window on the top slot only, so the layers beneath stay smooth.
A zipper pocket behind the bill pocket turns this into a coin-safe wallet, and the only real risk is that seam. Zipper tape is thick, so keep the tape ends clear of the 3/8 inch (1 cm) outer seam or that corner will be lumpy and the needle will deflect. Install the zipper into the pocket panel before that panel is stitched to the outer, while it is still a flat piece you can maneuver under the foot.
Finishing, pressing, and making it last
Press the wallet flat before you close the gap. With the wallet empty, work the seam to the edge and roll it between your thumb and finger so the outer fabric wraps just past the seam line and the lining disappears to the inside, then press. Do this first, then slip stitch the gap, then topstitch 1/8 inch (3 mm) around the outer edge; skipping the roll is why lining so often peeks out along topstitching.
Use polyester thread throughout, as listed, and treat both sides the same. At the mouth of the card slots and along the outer edge the thread is rubbed every time the wallet leaves a pocket, and cotton thread abrades through faster at exactly those spots. Matching the topstitching on the front and the back also makes the wallet look deliberate rather than improvised.
Press the fold last, with the wallet empty, and let it cool before you load it. Overstuffing is what wears a fabric wallet out: if it will not close without strain, the slot basting and the fold line carry the load, and the fold is the first place a bifold fails. Keep the bill pocket for bills rather than coins, since coins concentrate all their weight on a small area of the pocket seam.
For care, spot clean with mild soap and a damp cloth and leave it to air dry. Machine washing is the wrong move here because the fusible interfacing can delaminate and bubble, and tumbling distorts both the fold and a metal snap. If it needs more than a spot clean, hand wash cold, reshape it flat, and air dry. Close hook-and-loop tape before any wash so it does not snag the rest of the load, and if a snap works loose, re-stitch it through a small patch of fusible placed behind the fabric.
Frequently asked questions
- Do I need a walking foot to sew this wallet?
- No, but it helps. The hard part is the two side seams, where the machine crosses the card slot stack, both outer panels, and both linings at once. A walking foot feeds the top and bottom together so those layers do not shift. Without one, lengthen the stitch slightly, do not push the fabric, and turn the handwheel by hand through the thickest stretch. Each side seam is short, so it stays manageable even on a basic machine.
- How do I keep the six card slots evenly spaced, and how deep should they be?
- Press all six slot pieces the same way so each measures 8 x 1.5 inches (20 x 3.75 cm), then mark your placement lines on the lining with a ruler instead of eyeballing the overlap. Every offset is 3/4 inch (2 cm) and should be measured from the panel edge, never from the slot above it, because small errors stack up. After basting, check that the side edges of the stack are flush with the lining panel so the final 3/8 inch (1 cm) seam has one flat edge to follow.
- Can I leave off the bill pocket, or make the wallet without a lining?
- You can leave off the bill pocket, and the construction barely changes: the layer order for joining is the same and you simply have one less layer on that side, so the wallet turns and presses more easily. Cutting the lining is not a good idea, though. The card slots are basted to the lining panels, and the lining is what hides those basting stitches and gives the inside a clean finish every time the wallet opens.
- How do I wash the wallet, and will the fold wear out?
- Spot clean it with mild soap and a damp cloth and let it air dry; machine washing can delaminate the fusible interfacing and leave bubbles, and a dryer distorts the fold and any snap. The fold is the first place a bifold wears, so press it once with the wallet empty, let it cool, and only then load it. Avoid forcing a full wallet closed: if it closes easily, the fold and the slot stitching are not carrying any load.
