How to Sew a Fly Zipper on Pants
Zippers have been a part of men’s clothing since ancient times, and there are many different ways to sew on a zipper. Today, most zippers are sewn on with thread, which makes it one of the most convenient ways to add a zipper.
If you’ve ever sewn a pair of pants before, you know that sewing a fly zipper in them can be a hassle. So how to sew a fly zipper on pants? Here’s a step-by-step guide to help you out.
How to Sew a Fly Zipper on Pants Step by Step
Step 1: Sewing the Fly Zipper:
- First, you’ll need two pieces of denim to construct the fly. Cut your pieces on the bias (the slanted side). Then, fold one piece of fabric over the other and iron it flat.
- Next, cut off any extra length of denim. It should be the same width as the other pieces of fabric.
- Then, cut the excess fabric off the raw edges.
- Now that you have all of the pieces, fold the top piece over so the raw edge is facing down. This will be your base for sewing.
Step 2: Start Sewing:
- You’ll start by using a straight stitch to sew the bottom seam. Begin stitching with a sewing machine at a high speed. You want to keep the needle as close to the raw edge as possible.
- You’ll need to adjust the tension on the machine accordingly.
- Now, pull the presser foot off and put the machine in overlock mode. When you press down on the lever, the machine will automatically sew a chain stitch along the raw edge.
- Next, stitch around the entire seam.
- Continue sewing for about 15 seconds.
Step 3: Cutting the Bottom Seam:
- When you’ve finished sewing around the entire seam, take the presser foot off the machine. Now, you’ll need to cut away the excess material.
- Make a small snip on the right side of the fabric. This will release the excess material and prevent it from fraying.
- Repeat this process on the other side of the fabric.
Step 4: Sewing the Top Seam:
- Next, turn the fabric over so the wrong side is facing up.
- Start sewing again, this time on the top seam.
- As you sew, pull the bobbin thread to the right. This will help keep the stitches from being too loose.
- Stitch as close to the edge as possible.
- Pull the bobbin thread to the left and back.
- Continue doing this until the top seam is complete.
Step 5: Finish the Zipper:
- Take your first piece of fabric and turn it right side out.
- Flatten the seam, and then stitch the sides closed.
- Repeat this step with the second piece of fabric.
Step 6: Cut the Zipper:
- You’ll need to cut the zipper tape so it will fit inside the zipper.
- Make a slit across the top of the fabric.
- Next, remove the top tab of the zipper.
- Finally, use the tab to measure where you’d like to cut the zipper.
- Using scissors, carefully cut the tape in between the slits.
Step 7: Install the Zipper:
- First, place the slider into the slot in the middle of the zipper.
- Next, turn the zipper pull on the right.
- Pull the slider until the tab is hidden behind the zipper teeth.
- Tuck the end of the zipper underneath the top of the zipper.
Step 8: Cut the Tabs:
- The last step is to cut away the extra tabs on the sides of the zipper.
- To do this, turn the zipper over and use the tab that’s facing down to measure where you’d like to cut.
- Using a pair of scissors, carefully cut the excess material.
Step 9: Attach the Hook and Eye:
- It’s time to attach the hook and eye. First, turn the zipper pull on the right.
- Next, slide the loop of the hook over the eye.
- Grip the loop tightly so it doesn’t fall off.
- Slide the hook back through the loop.
- Repeat this step on the other side.
Step 10: Try It Out:
- Now that you’ve created a basic fly zipper, you’re ready to try it on some pants or jeans.
- First, lay the zipper on top of your pants.
- Stitch the bottom seam of your pants together.
- Now, flip the pants inside out and slide them down your body.
- Check to make sure that the fly fits appropriately.
- If you don’t like the way it looks, you can always alter it further.
- You can see a few things I did differently here. First, I added a small piece of fabric along the inside seam.
Methods to Sew a Fly Zipper
There are two different ways to sew a fly zipper. One is called the double-back method, and the other is called the single-back method.
The double-back method, also known as the double-barrel method, involves sewing two rows of stitching along each side of the fly.
This method is best for making a perfect, smooth stitch. There’s also less chance of it falling apart.
The single-back method is also known as the single-barrel method. This method involves sewing a single row of stitching around the entire fly.
This method is best for making sure there aren’t any holes in the seam. It’s also easier to do and can be done by hand.
