I’m someone who likes having a pouch for everything. Chapstick, bobby pins, headphones, tea packets, charging cables — you name it! I had so much fun making my first key chain pouch pattern that I decided I needed another one. Because who doesn’t need an excuse to sew more cute pouches?

This pouch comes in five sizes, so you can make one to fit basically any little item you want to keep in its own zippered pouch. Each size has its own benefits, but my favorite is by far the smallest size. It’s possibly the cutest pouch I’ve ever made.

Before designing this pattern, I didn’t think it would be possible to make such a teeny tiny zipper pouch, let alone fit anything useful in it. But it turns out to be the perfect size for bobby pins. You can also fit a house key in it — great if you want to take a walk without bringing your whole key chain. It’s now my favorite pouch of the bunch and I can’t help but smile when I look at it!

Whatever size you make, this might be the easiest zipper pouch you ever sew. And perhaps best of all, it doesn’t have any raw seams, and you don’t need to do any binding to cover exposed edges. Aside from super basic sewing supplies, the only special equipment you need is a zipper foot, a zipper, and some key chain hardware.

Supplies & Tools

• Quilting fabric or other woven fabric
• Quilt batting (optional)
• Spray adhesive such as ODIF 505 (unless you are using fusible batting)
• Straight pins or quilting clips
• Sewing machine
• Zipper foot (or get this set with every foot imaginable!)
• Regular sewing machine foot
• Matching thread
• Iron & Ironing board
• Cutting mat
• Key chain hardware such as jump rings or lobster key chain clips
• 6 to 8″ zipper (this is a cool set because it comes with multiple sizes)

You can actually find some nice fabric on Amazon, but I love using Green Fairy Quilts for specialty quilting fabric.

Step 1: Cutting the Pieces and Attaching Batting

You’ll notice that the pattern comes in 5 different sizes, so you can cut out whichever size you want to make. Be sure to cut the outer fabric and batting on the fold, as indicated by the pattern.

I put some triangle markings on the pattern to help indicate what side of the fabric to use for different steps in the process. You don’t need to transfer these to the fabric, but it may help. I use tailor’s chalk or a fabric pen to draw a little line rather than cutting the triangle in the fabric itself.

After cutting the pieces, you’ll attach the batting to the wrong side of the outer fabric, lining up the triangles as a guide. You can use fusible batting or use fabric adhesive like Odif 505 to attach the batting.

Step 2: Preparing the Key Chain Loop

1. Fold the marked edges of the keychain loop towards the center of the wrong side of the fabric until the edges meet in the middle.
2. Press the fabric, then fold it in half so the raw edges you just folded under are tucked inside. Press again.
3. Sew along both folded edges, sewing as close as possible to the edge while still catching all the layers.

Note: Depending on the key chain hardware you have, you may want to slide it over the loop now so you don’t forget. Not all styles can be attached after sewing the loop to the bag. I like doing this even though I use jump rings — it just makes everything easier.

After sliding the hardware over the loop, I also like to do some basting stitches along the raw edge so I don’t need to worry about keeping the loop folded.

Step 3: Attaching the Zipper

I find it’s easiest to leave the zipper closed when attaching it. I like using a slightly longer zipper so it extends beyond the ends of the fabric. You can trim off the excess later.

Lay your OUTER FABRIC right side (RS) up towards you on the table. Then place the zipper face down on the fabric along one of the edges marked with a triangle.

Place one piece of LINER fabric wrong side (WS) down on top of the zipper, lining up the edge marked with a triangle.

Pin the “sandwich” together, then using a zipper foot, sew the layers together with a 1/4″ seam allowance.

After sewing the first side, place the fabric sandwich so the OUTER FABRIC is right side (RS) towards you on the table. Then fold the sandwich so that the other edge of the zipper tape lays over the un-sewn edge of the OUTER FABRIC. The zipper will be face down.

Make sure the fabric edges are lined up neatly and the zipper is laying flat (the bag will not line up if the zipper isn’t aligned neatly across the top).

Next, lay the remaining piece of LINER fabric RS down on top of the zipper. Pin along the edge, then sew the layers together with a 1/4″ seam allowance.

Press the fabric away from the zipper with your iron.

Lastly, topstitch along both edges of the zipper close to the edge of the fabric. I find it helps to unzip the zipper before doing the topstitching.

Step 4: Sewing the Bottom of the Liner

Next we need to sew the bottom of the liner. We’ll leave a gap in the middle so the bag can be turned after the last step.

1. Fold the pouch so the liner fabric pieces are RS together and pin along the bottom edge.
2. Using a 1/4″ seam allowance, stitch about 1″ on both ends of the liner, leaving a gap about 2-3″ in length (depending on size of pouch you’re making).
3. After sewing, press the seam open.

Step 5: Sewing the Ends of the Pouch

Fold the pouch so that the zipper is in the middle. You’ll notice that the liner isn’t as wide as the outer fabric. This is on purpose so that the liner isn’t bunchy inside the pouch.

Make sure the zipper pull is in the pouch, not outside it. However, don’t close the zipper all the way or you won’t be able to turn the bag!

Fold the key chain loop in half and insert it between the OUTER FABRIC and zipper. Place it at the end where the zipper will close when zipped. Center the loop over the zipper tape with the folded edge inside the pouch.

Pin along both raw edges, making sure that the key chain loop remains centered.

Then, using a 1/4″ seam allowance, sew through all layers on both ends of the pouch. Make sure to backstitch the ends. You may also want to backstitch again over the key chain loop.

Step 6: Finishing the Bag

Trim off the excess zipper tape after sewing the ends. I also like to clip the corners of the pouch so they can be nice and pointy after turning the bag.

Turn the bag right side out and use a blunt tool to poke out all four corners.

Lastly, stitch the opening with an invisible ladder stitch.

Happy Sewing!

I had so much fun designing this pattern, and I hope you love these little keychain pouches as much as I do! I’d love to hear how this project goes for you in the comments. You can also share photos on social media with #CraftingWithClementine so I can see what you made!
