How to Sew a Pouch With a Recessed Zipper and Boxed Base

The closure has three parts: a zipper, two narrow fabric strips beside it, and an upper lining band above its attachment seam. Here, “zipper bridge” means the complete zipper-and-strip assembly.

This project uses free panel ends, which remain loose inside the pouch. Bethany Lynne Makes distinguishes this construction from an enclosed-end zipper, whose panel ends are sewn into the bag sides. The free ends leave small openings beside the bridge, so choose this version for items larger than those openings. How to Sew a Recessed Zipper (Open End Method)

Use quilting cotton for the exterior, lining and zipper strips. For a firmer exterior, add lightweight fusible interfacing according to its manufacturer’s instructions. Keep the first version free of thick padding so the small seams remain manageable.

You also need a sewing machine, zipper foot, coordinating thread, ruler, fabric marker, scissors, pins or clips, an iron and a hand-sewing needle. Select a conventional nylon-coil zipper at least 14 inches long, with an installed slider and tape measuring approximately 1 inch across when closed. The tape width matters to the bridge calculation below.

All measurements are in inches, with width listed first. Use a ¼-inch construction seam allowance throughout; topstitch approximately ⅛ inch from folded edges.

Piece	Quantity	Cut size
Exterior	2	11 × 8
Optional exterior interfacing	2	11 × 8
Upper lining band	2	11 × 1½
Lower lining	2	11 × 7
Zipper strips, upper and underside layers	4	10 × 1¼
Zipper end caps	2	2 × 2

Mark the center of every 11-inch lining edge and every zipper strip. Keep directional prints upright on both exterior pieces.

Check the dimensions before sewing

The assembled lining must match the exterior height: 1½ + 7 − ½ = 8 inches. The half-inch deduction accounts for the two seam allowances where the upper and lower lining meet. Sewing Novice uses this same check when dividing a lining to accommodate a recessed zipper. Recessed Zipper Tutorial

The upper lining band finishes 1 inch high between its attachment seam and the rim: 1½ − ¼ − ¼ = 1 inch. Folding each zipper strip’s short ends under ¼ inch produces a 9½-inch finished length. Centered on the 11-inch lining, that leaves ¾ inch at each raw side edge, including the side seam allowance.

For the bridge width, let T equal the full width of the closed zipper tape and P equal the cut width of one strip. With ¼-inch seams, the finished bridge width is 2P + T − 1½. Here, 2(1¼) + 1 − 1½ = 2 inches. If your tape differs, calculate P = (3½ − T) ÷ 2 before cutting. This keeps the bridge close to the planned base depth.

Press both short ends of all four zipper strips under ¼ inch, toward the wrong side. Leave their long edges unfolded.

Place one strip right side up. Lay the zipper face down on it, aligning one tape edge with a long raw fabric edge. Center the strip along a usable section of zipper, leaving excess zipper beyond both folded ends. Add a second strip right side down, matching its folds and raw edges to the first.

Using a zipper foot, sew through the three layers ¼ inch from the aligned long edge. Fold both fabric layers away from the coil, with wrong sides together. Repeat on the other zipper tape using the remaining strips. Fabric-and-zipper sandwiches followed by pressing and topstitching are also demonstrated in Bethany Lynne Makes’ enclosed-end tutorial; only that shared attachment technique is used here.

Topstitch beside the coil through both layers of each strip. Stitch each folded short end closed, stopping at the zipper tape. Leave the two outer long edges raw for attachment to the lining. Check that the strips begin and end together and that the slider travels without catching fabric.

Measure across the bridge between the future lining attachment lines, each ¼ inch inside an outer raw edge. It should measure approximately 2 inches. Correct an uneven zipper seam now, while the assembly is flat.

Mark a cutting line on the zipper 1 inch beyond each finished strip end. The retained tape will be 11½ inches long. Move the slider between those marks before trimming.

Make firm hand-sewn thread stops across the coil about ¼ inch inside each cutting line. At the opening end, align the two zipper halves and join them together with the stop stitches. Keep any existing hard stops outside the later cap stitching. Cut on the marked lines only after confirming that the slider remains between the new stops. Thread stops before trimming are described in I Can Sew This’s zipper-pouch instructions. How to sew a lined zipper pouch with zipper tabs – 5 simple steps

For each 2-inch-square cap, press two opposite edges under ¼ inch, creating a 1½ × 2-inch rectangle. Fold the 2-inch length in half and press. Open that fold, bring both remaining raw ends to the center crease, then fold the cap closed again. It now measures approximately 1½ inches across and ½ inch deep.

Slip a cap over each cut zipper end, placing the cut edge against the cap’s outer fold. Stitch around the cap’s open edges, using hand stitches where needed across the coil. Confirm that both stops remain covered and the slider stays on the zipper. Leave these capped tails free inside the finished pouch.

Lay one lower lining piece right side up, with its 11-inch top edge horizontal. Place the bridge face up on it, matching one outer raw bridge edge to that top edge and aligning their centers. The bridge’s opposite edge extends down over the lining.

Place an upper lining band right side down on top, matching its bottom edge to the same raw edge. Sew across the full 11-inch width at ¼ inch, catching the bridge between the lining pieces. This split-lining sandwich follows the attachment arrangement in Sewing Novice’s tutorial. Recessed Zipper Tutorial

Open the lining pieces into one flat panel and press the joining allowances toward the upper band. Fold the bridge upward over that band temporarily. Repeat with the other bridge edge and the remaining lining pieces, keeping the first completed side out of the stitching.

Lay both lining sides out and check their orientation. The zipper pull must face toward the upper bands—the direction of the eventual pouch opening. Each assembled lining side should measure 11 × 8 inches, and the two horizontal joining seams should align at the side edges.

Place the exterior pieces right sides together. Sew both sides and the bottom at ¼ inch, leaving the top open. Sew the lining sides and bottom similarly, but leave a 4-inch turning gap in the center of its bottom seam. Keep the bridge and capped tails clear of the lining side seams.

To box an exterior corner, pull its fabric layers apart and flatten the corner into a triangle, aligning the side seam directly over the bottom seam. Draw a line perpendicular to those seams where the triangle measures 2 inches across, fold to fold. Sew on that line, then trim the point away, leaving a ¼-inch allowance.

Repeat for the other exterior corner and both lining corners. Sew4Home explains that the stitching line’s fold-to-fold length determines the finished depth; alternatively, a 2-inch corner can be marked 1 inch from the stitched corner intersection. Matching the side and bottom seams keeps the base square. How To Box Corners

For these dimensions, the calculated base width is 11 − ½ − 2 = 8½ inches. The height is 8 − ½ − 1 = 6½ inches, allowing for the top and bottom seams and the height consumed by the boxed base.

Open the zipper at least halfway. Turn the exterior right side out, leaving the lining wrong side out. Place the exterior inside the lining, with their right sides touching. Match the raw top edges and side seams, keeping the zipper assembly down inside and clear of the rim.

Sew around the entire top at ¼ inch. Pull the exterior through the lining’s bottom gap, then arrange the lining inside the pouch. Leaving a lining opening and turning through it is also the finishing method used in I Can Sew This’s lined-pouch tutorial. How to sew a lined zipper pouch with zipper tabs – 5 simple steps

Roll the top seam until the exterior and lining meet neatly at the rim. Press, then topstitch around the opening approximately ⅛ inch from the edge. Move the free zipper tails away as you work.

Check the lining fit and operate the zipper before closing the turning gap. Fold the gap’s seam allowances inward ¼ inch and close it with a narrow machine seam or hand ladder stitch.

Use these checks while the turning opening still gives access to the seams. They follow from the dimensions and layer arrangement in this project.

Symptom	What to check	Correction
Slider catches fabric	Fabric folds crowd the coil	Release the affected topstitching, move the fabric away and restitch
Bridge pulls the sides inward	Width between attachment seams is less than planned	Recheck tape width and the strip-width calculation
One bridge end sits higher	Strip ends or lining centers were mismatched	Reposition that attachment before finishing
Lining twists	Side seams or boxed corners are misaligned	Match corresponding seams and corners before closing the gap
Zipper sits too near the rim	Upper bands were cut short or sewn with larger allowances	Verify the 1½-inch cut height and both ¼-inch seams

Before the final press, flatten the base, settle each lining corner into its matching exterior corner and open and close the zipper several times. The finished pouch should have an even rim, a closure resting about 1 inch below it and free capped tails tucked inside. Keep the cutting dimensions and your measured zipper-tape width together so the same construction is straightforward to repeat.
