Prepare the Fabric – How to Sew a Clam Shell Zipper Pouch
Before cutting your pouch, fuse the woven interfacing to the wrong side of either the exterior or lining fabric.

If you’re working with patchwork, sew your fabric squares together first before trimming the panel to the finished size of 12 inches x 8 inches.

Fold the pouch in half lengthwise with the lining fabric facing outward.
Secure both sides using sewing clips.
Mark a 1-inch boxed corner on each bottom corner using a friction pen.
Next, unfold the pouch and locate the exact centre by folding it in half.
Mark the centre point.
Refold the fabric and draw a smooth curved line from the centre point down to the boxed corner.
This curved shape creates the distinctive clam shell appearance.
Carefully cut:
- The boxed corner
- The curved edge
Open the fabric and use the first side as your guide for cutting the opposite side.
If the curve appears slightly pointed, simply trim it until you’re happy with the shape.
Add the Binding – How to Sew a Clam Shell Zipper Pouch
Before installing the zipper, finish both curved edges with your binding.
Attach the binding along each curved edge.
Press thoroughly after sewing.
A good press helps the curved edges lie perfectly flat and makes zipper installation much easier.

Place the pouch with the exterior fabric facing upward.
Position the zipper with the zipper teeth facing upward as well.
Allow the zipper tape to extend slightly beyond both ends of the pouch.
Sew the zipper onto one curved edge.
Repeat for the opposite side.
Once both sides are attached, reinstall the zipper pull onto the zipper tape.
Trim away the excess zipper tape so it is even with the pouch.
Make the Zipper Tabs – How to Sew a Clam Shell Zipper Pouch
The zipper tabs give your project a professional finish while protecting the zipper ends.
Take each 3-inch square.
Fold in half and press.
Open.
Fold both raw edges into the centre.
Fold again.
Topstitch along both long edges just as you would when making a bag handle.
Fold each finished strip into a loop.
Place one loop over each zipper end.
Stitch securely across the ends.
Sew the Boxed Corners – How to Sew a Clam Shell Zipper Pouch
Open the zipper halfway before sewing.
This is important because it allows you to turn the pouch right side out later.
Match each boxed corner seam.
Clip into place.
Sew straight across each boxed corner.
These seams create depth and allow the pouch to stand nicely once finished.
Create the Interior Flaps – How to Sew a Clam Shell Zipper Pouch
One feature that makes this pouch unique is the interior flap.
These flaps help stop smaller items from slipping out whenever the zipper is opened.
Take each 7-inch x 3-inch fabric strip.
Fold in half.
Sew along the folded edge.
Position each flap over the boxed corner opening.
Align the raw edges.
Clip securely.
Stitch across the opening.
Fold any remaining raw edges underneath before sewing them down.
Take your time with this step.
The layers can become slightly bulky, but sewing slowly produces the neatest finish.
Finish the Inside – How to Sew a Clam Shell Zipper Pouch
After the flaps are sewn into place, cover all remaining raw edges with binding.
Binding gives the pouch a beautifully finished interior while hiding every raw seam.
Unlike many simple zipper pouches, this method leaves the inside looking clean and professional.
Once the binding has been attached, turn the pouch right side out.
If you notice any small sections that weren’t completely stitched, simply turn the pouch back inside out and sew those areas before turning it right side out again.
