Eleven zipper pouch patterns, each one giving the cut size, the zip length it needs and where the zip ends go. The puckered zip and the lumpy corner both come from the same missing number, and almost no free tutorial states it.
Quick answer: The zip should be at least 1 in longer than the finished width of the pouch, and the metal or plastic stops at both ends must sit outside the side seams. Start with a 9 x 7 in cut and a 9 in zip, which finishes at about 8 x 6 in. Sew with a zipper foot and a stitch length of 2.5, and stitch the zip on with the pull moved out of the way halfway along.
The Number Every Pouch Tutorial Skips
A zip fails in a pouch for one of two reasons, and neither is sewing skill. Either the zip is exactly as long as the pouch, so the stops land in the side seams and the corner will not turn out, or the zip is too long and the tape flaps loose at the end. Both are decided before you sew, when you buy the zip.
The rule is worth memorising because it never changes: zip length = cut width of the pouch, or 1 to 2 in more. A 9 in wide cut piece takes a 9 in zip and the stops sit right on the seam allowance, which is fine. A 7 in wide cut piece takes a 7 or 9 in zip, and a 9 in zip gets trimmed after the side seams are sewn, never before.
Trimming after is the part that gets left out. Sew the zip in, sew the sides, then cut the excess tape flush with the side seam. Cut it first and the stop is gone, the pull runs off the end, and the pouch is finished.
Fabric, and Why It Matters More Here Than in a Bag
Of 1,300 sewing posts we read, only 163 named a fabric at all. On a tote that is careless. On a pouch it decides the outcome, because the whole thing is corners and a pouch corner is four to six layers thick.
- Quilting cotton, the most named fabric in that sample at 59 mentions, is the right weight for a pouch. It turns out at the corner and takes a press.
- Canvas or denim makes a pouch that stands, but the corners get thick enough to need a 90/14 needle and a slow hand.
- Linen frays at every raw edge, so it needs lining, which every pouch below has anyway.
- Laminated cotton or oilcloth does not fray and does not need lining, but it will not un-sew: every needle hole is permanent.
Fusible fleece or foam interfacing on the outer pieces is what separates a pouch that holds its shape from one that folds flat in a drawer. It changes no measurement.
Eleven Pouches, With the Zip Length Named
1. Basic flat pouch
Two outer 9 x 7 in, two lining 9 x 7 in, one 9 in zip. Finished about 8 x 6 in. Sandwich the zip between one outer and one lining, right sides facing the zip, and topstitch. Repeat on the other side, then sew outer to outer and lining to lining with the zip half open.
2. Pencil case
Two outer 9 x 4.5 in, two lining the same, one 9 in zip. Finished about 8 x 3.5 in. The narrowest pouch worth making, because below this the zip foot cannot clear the seam.
3. Boxy pouch, 2 in base
Two outer 9 x 8 in, two lining the same, one 9 in zip, 2 in boxed corners on both layers. Finished about 8 x 5 x 2 in. Box the corners after the side seams, the same triangle method a tote uses.
4. Boxy pouch, 4 in base
Two outer 11 x 10 in, two lining the same, one 12 in zip, 4 in boxed corners. Finished about 9 x 5 x 4 in. This is the one that stands open on a desk.
5. Wide makeup bag
Two outer 11 x 8 in, two lining the same, one 12 in zip, 3 in boxed corners. Finished about 10 x 5 x 3 in. Line it in laminated cotton and skip the interfacing there, since the laminate stiffens it.
6. Small coin pouch
Two outer 5 x 4.5 in, two lining the same, one 5 in zip. Finished about 4 x 3.5 in. Fiddly rather than hard, and a good use for the offcut left over from a bigger pouch.
7. Wristlet pouch
Basic flat pouch plus a strap cut 12 x 2.5 in, folded into a four-layer 5/8 in strap and caught in the right-hand side seam before it is sewn. Catch it after and there is no way to attach it invisibly.
8. Divided pouch
Basic flat pouch with the lining cut 9 x 13 in instead of two 9 x 7 in pieces, folded so it makes its own inner wall. One 9 in zip. The wall stops small things migrating under everything else.
9. Zip-top pouch with a flat bottom seam
One outer cut 9 x 14 in folded in half rather than two pieces, one lining the same, one 9 in zip. Finished about 8 x 6 in with no bottom seam at all, which is one less place to go wrong.
10. Triangle pouch
Two outer 9 x 7 in, two lining, one 9 in zip. Sew it as a flat pouch, then at the bottom match the two side seams to each other and sew straight across, so the base forms one seam perpendicular to the zip. Finished as a wedge.
11. Double-zip pouch
Three outer 9 x 5 in, three lining, two 9 in zips. Two compartments back to back sharing a middle panel. It is the flat pouch done twice, and worth doing only after the flat pouch has stopped puckering.
The Four Things That Go Wrong
The stitching wobbles around the zip pull
Stop with the needle down about halfway along, lift the presser foot, slide the pull past the needle behind the foot, drop the foot and carry on. Sewing around the pull is the whole cause.
The zip puckers
The fabric fed faster than the tape. Hold the layers taut without pulling them through, use a stitch length of 2.5, and press the seam away from the zip before topstitching.
The corners are lumpy
Trim the corner seam allowance back to about 1/8 in before turning, and push the corner out with something blunt. A pointed tool goes straight through the stitching.
The lining shows at the top edge
Press the outer and lining away from the zip tape and topstitch about 1/8 in from the fold on both sides. That topstitch is the only thing holding the lining back.
What the Zip Actually Needs From the Machine
A zipper foot, which is the narrow one that lets the needle run close to the teeth. Stitch length 2.5, needle in the centre unless the foot moves it. A universal 80/12 needle is fine for cotton; go to 90/14 once you have interfacing plus canvas plus lining stacked at a corner.
Zipper Pouch FAQ
What size zip do I need for a pouch?
The same as the cut width of the pouch, or 1 to 2 in longer. For a 9 x 7 in cut, a 9 in zip. If the zip is longer, sew everything first and trim the tape flush with the side seam afterwards.
Why does my zip pucker?
The fabric fed through faster than the zip tape. Keep the layers taut, use a stitch length of 2.5, and press away from the zip before you topstitch.
Can I sew a zip without a zipper foot?
You can, but the stitching will sit further from the teeth and the pouch will look it. A zipper foot is the one attachment worth having before the first pouch.
How do I sew past the zip pull?
Stop halfway with the needle down, lift the foot, slide the pull behind the needle, drop the foot, continue. The stitch line stays straight because the needle never left the fabric.
What is the easiest zipper pouch for a first try?
The flat pouch at 9 x 7 in with a 9 in zip. No boxed corners, no strap, four pieces and one zip, and about forty minutes.
