Ever found yourself in need of small zip lock bags but couldn't find the right size? Or perhaps you're looking to reduce plastic waste and want to make your own reusable bags? Either way, making your own small zip lock bags is a simple, cost-effective, and eco-friendly solution. Here's a step-by-step guide to help you create your own, perfect for snacks, small parts, or even as a DIY gift.
Materials Needed
Before you start, gather your materials. You'll need:
- Fabric (heavy-duty, water-resistant, and easy to clean, like ripstop nylon or polyester)
- Zipper (small, water-resistant, and easy to slide)
- Sewing machine (optional, but recommended for a neat finish)
- Scissors
- Ruler or measuring tape
- Pins
- Thread (matching your fabric)
Measure and Cut
The first step is to determine the size of your bag. For small bags, aim for around 4" x 6" or adjust to your desired dimensions. Once you've decided, use your ruler or measuring tape to mark out the size on your fabric, then cut out two identical pieces.

For the zipper, you'll need a piece slightly longer than the width of your bag. A good rule of thumb is to add about 1/4" to 1/2" to each side for seam allowance.
Prepare the Zipper
Before sewing, prepare your zipper. If it's not already open, separate the two sides. Then, press the zipper teeth flat to make sewing easier.
Sew the Sides
Start by sewing the two fabric pieces together along the two longer sides. Place the pieces right sides together, align the edges, and sew using a straight stitch, leaving the top open.

Press the seam allowance open to reduce bulk and make it easier to work with.
Add the Zipper
Now it's time to attach the zipper. Place the zipper along the open edge of your bag, right sides together. Make sure the zipper is centered and the teeth are facing the inside of the bag.
Sew along the edge of the zipper, using a straight stitch. Backstitch at the beginning and end for extra strength. Once sewn, press the seam allowance open.

Sew the Bottom
If you want a flat bottom, fold the bottom edge of your bag up about 1/2" and press. Then, fold it up again to create a hem, and press. Sew along the edge to create a flat bottom.
Alternatively, for a rounded bottom, simply sew the bottom edge closed, using a curved or straight stitch.
Finish the Top
To finish the top edge, fold the raw edge over to the wrong side by about 1/4" and press. Then, fold it over again to enclose the raw edge, creating a neat finish. Sew along the edge to secure.
Now, try zipping and unzipping your bag to ensure it works smoothly. If needed, trim any excess fabric or threads.
Optional: Add a Label or Tag
For a personal touch, consider adding a label or tag to your bag. This could be a simple fabric tag with your initials, or a fun design to make it stand out.
And there you have it! Your very own small zip lock bag, ready to use and reuse. Whether you're organizing, storing, or sharing, these bags are a practical and eco-friendly solution. Happy sewing!
