How to Fix a Zipper Tab in A Fly Zipper

How to Fix a Zipper Tab in A Fly Zipper


Did your slider tab break and you need to
replace it on a fly zipper? This video will show you how to make this
fix so that your garment is as good as new. To make this fix, you’ll need your pants,
seam ripper, zipper repair kit, needle, thread, needle nose pliers and a product to stop fabric
fraying. Looking at the inside of the pants, use your
seam ripper and carefully remove the stitches holding the fly guard to the fly facing. Then remove the stitches holding the zipper
tape to the fly facing to about 1” to 2” up from the bottom of the zipper. There may be two rows of stitches and you’ll
have to remove both. Next, remove the stitches between the fly
guard and the zipper, again going 1-2” up from the bottom. The bottom of your zipper should be free from
the pants, like this. At the bottom is a zipper stop which will
need to be removed. It’s difficult so I’m going to cut mine
off. Don’t use expensive dressmaker shears for
this part. Now that the zipper stop is off, you can pull
off the old slider. Before you toss the old slider, look at the
back. Mine says 4.5. I can use this information to find the correct
replacement slider from my zipper repair kit. Look at the right side of the pants with the
right side of the slider facing up .
Take your new slider and place it at the bottom of the zipper, making sure each side of the
zipper teeth is lined up as perfectly as possible. If you do it correctly, when you pull up on
the slider, the teeth will lock together. In your repair kit, you might also have a
zipper stop. Looking at the right side of the zipper, push
the new stop at the very bottom. The zipper stop prongs go from the right side
of the zipper to the wrong side. On the wrong side of the zipper, use your
pliers to press the prongs over the zipper teeth to lock in place. If you don’t have a zipper stop, stitch
over the teeth with some hand whip stitches. You can also see an example of this in our
How to Shorten a Zipper tutorial. Apply a product that stops fabric fraying
to the bottom of the zipper tape and let it dry completely. Now we just have to resew our zipper back
into place by reversing how we removed it. I’m using jeans top stitching thread on a hand needle. The first sewing I am going to do. is closing up this is my fly guard, where the fly guard seam meets the zipper seam and also meets this part of the pants seam So it’s a pretty thick area where you are trying to sew in. Im just showing you where it is going to happen. This is where I took out my stitches from the bottom of the zipper up until this point. So i’m going to start up here. And i’m not saying that you can’t do this on the sewing machine, you can kinda see, especially with the zipper tab and also this area, it gets really tight, so trying to get your sewing needle from your machine into this area is going to be really difficult. And it’s only about an inch so i’m just going to go ahead and do it by hand. You will also notice I didn’t remove my old thread. Im just going to leave it in. You can remove it if you want. But for me I am just using it as a guide. Where I need to stitch in order to match the previous stitches above it. And also how big to make the stitches. I’m just going to stitch right on top of it, I am going to do a back stitch. So this is the end of one previous stitch I did, I am going a little bit in front of that, about 1/8 of an inch. And I put in a straight pin to make sure my zipper tape stays in place. And then going back to the previous stitch. That’s why its called a back stitch, you are going a little bit forward and then moving you needle back. And you will notice my thread does not exactly match. But once this is closed, when you close your zipper you are not even going to notice it. So now I’m going to go a little bit in front. Of that previous stitch. And then go back. To my first stitch. I’ve done 3 stitches, so now I am going to go in front of that stitch and the go back again. So that’s all the back stitch is. You are going up 1/8 of an inch. and then going back to the previous stitch. and just go, you might not be able to go all the way completely down to the bottom of the zipper, just go as far as you can go. On my last stitch I was looking at the right side of my jeans. And the reason why is because I want to make sure since that stitch is on the right side and you will see it. It’s going to look as neat as possible so I have a little bit more control if I am looking at the right side when I am hand sewing it as it might not look so great when you are looking at the back. Now this second part of stitching, we are still going to do a back stitch but it is a trickier. its attaching the bottom part of our zipper tape to our fly facing, which is this section right here. This normally, when you are constructing your jeans. This tape. is sewn.. we had our 2 rows of stitches , is sewn to the fly facing. Before the fly facing is actually attached to the pants. So that’s why you don’t see these 2 rows of stitches on the right side of your jeans. So we want to make sure, when we stitch this in to place, we are not putting our needle clear through To the pants side and we are going to see the stitches on the right side So I’m going to actually going to start off by picking a matching color thread. In this case it would be dark, but in my example I am going to use contrasting so you can see it, buy you want to use a matching one. I went head and pinned my tape to the pants so it will stay in place. And also pinned my fly guard out of the way, so I don’t have to worry about it. going over when I am trying to sew it. Doing the back stitch again, I am going to go a little bit forward. from where I want my stitch to be and I am just going through the tape at this point, so I can hide my know, fairly easily. When I put my needle down, I am going deep enough to try to grab this fly facing fabric. And I have my finger actually right directly under this part, so if I go too deep and I go through the other side I’m actually going to prick my finger and I am going to feel that, so that’s how I know If I don’t stick myself, that how I know I didn’t go to deep. So that would be my first stitch. and you know you actually grabbed the fabric if you try and lift up the tape. and you can see your stitch going into the fabric. So now I am a little bit in front of that, I am going to go back to my first stitch. go through, try not to go all the way through go a little bit in front of that about an 1/8 of an inch. and I am trying to put it where the previous stitch was. trying to do straight, so I actually meet up with the original stitch you can see because I am using a contrasting thread, it’s not perfectly straight. but if you are using a matching color you are not even going to notice, and again, this is on the inside so it’s not that big of a deal. so I am going back to the second stitch and a little bit in front of that one. Once I actually meet up with the original stitch, which is hard to see because it is the same color. I’m actually going to go a few stitches into the old one. and then tie a knot, which you can see right there. That way I kind of lock off the new stitch with the old stitch. so it does not come further undone. right now since I took out all these stitches, there is no knot here so this can just keep unraveling and I don’t want that to happen. So I’ll just do a few stitches into the original one just to hold it in place and hopefully it wont become undone any further. lastly, we are going to sew our fly guard back in place over the fly facing. So I have been holding it in place to keep it out of the way. Im going to move it back, this was the first stitch we took out, which was right here. I’m going to put a pin to hold it and flip it to the right side because again, this is one of those that I want to look as neat as possible so I am going to look at the right side when I stitch it. We are back to looking at the right side of the pants for this last stitch. Now this you can definitely do on your machine if you just want to do it really quickly it’s basically a very narrow zig zag stitch or a type of satin stitch, you can see something similar right here. and where this is thicker, that’s where the original stitch was So I’m just going to do it by hand because it doesn’t really take that long. I’m always coming up on one side of these stitches here and then going down on the other side. so you are just doing, very short stitches that are stacked on top of each other for the whole length, and this time you can definitely go all the way through your pants so you don’t have to worry about doing a very shallow stitch. because we are making sure that we are attaching the fly guard to the pants. And that’s it. And here we have the zipper fly with a new slider. this task is a little time consuming but it will keep your jeans looking good, with a barely noticeable repair.

  1. Great tutorial! Normally I wouldn't want to do this type of repair – but for a favorite pair of jeans it would be so worth it! Thanks, PP!
