Have you ever tried to hem a pair of pants and by the time you were nearly finished sewing it, you realized that you were going to get puckers?
It happens to the best of us.
But, how do you avoid it?
I couldn’t find the answer anywhere in books or on the internet, so I devised my own method many years ago and it works like a charm.
I should probably try to patent it or something, but I’ll put it out there for the world to see today. Just remember you heard it here first!
To begin with, follow the post on How to Hem Pants and Skirts. Do everything it says to do up to and including the 7th photo. That means, you’ll be marking the new hemline, pressing it, and trimming off the excess.
After picture #7, the next paragraph shows how to tell if your pants are straight legged or not.
That post covers how to hem straight legs.
This one is for your tapered and flared pants.
If they are tapered (they get increasingly narrow as they approach the hem), then follow these next steps.
If they are flared, we’ll cover that below.
For a tapered pant:
If you fold up the pants at the new hemline, you’ll see that the new cut edge does not lay flat against the pant leg. There is excess pant leg material as shown in this mock pair:

So, this means we either have to narrow the pant leg above the foldline or increase the diameter of the hem below the foldline to get them to lay flat.
(To know how much this amount is, pinch the excess above the cut edge and that will tell you how much you need.)
It’s usually enough to increase the amount below the foldline. As you can see by the red stitching line, I have stitched from the foldline out diagonally to the serged area:

Now, take out the original stitches of the seam from the fold straight down to the cut edge. In the above photo, it’s the black seamline to the left of the red one.
In the photo below, I’m using a real pair of pants to demonstrate this:

Many times, the manufacturer will use a chain stitch for this seam and you can rip out a stitch and pull it and the whole thing comes out quickly in one long thread.
Next, press that area flat:

Do both the inseam and the outseam of the first leg this way.
Now, fold the hem on the foldline and check to see if it lies flat.

If it does lay flat, do the same thing to the other leg. Then follow the instructions just after the 8th photo in How To Hem Pants and Skirts.
If there is still too much excess in the pant leg, you’ll need to take some out of the area above the foldline (since you’ve increased all you can below the foldline.) It’s never usually very much, maybe another 1/4″ amount.
Stitch a seam (as represented in red) gradually out from about 6 inches above the foldline. keeping that 1/4″ distance until just before you reach the foldline. If you don’t, the cut edge will still not lay flat. Stop right at the foldline.

You can trim the seam a little if you want, but it’s not necessary.
If you have a flared leg pant, you’ll want to do the opposite:

Stitch straight down from the foldline to the cut edge (red stitching line).
Then, make sure your hem lies flat.
Fold up the hemline and follow the directions after the 8th photo in “How To Hem Your Pants and Skirts”. Or, if you are hemming jeans, go to the post on “How To Hem Your Jeans the Professional Way”.
Any questions?
Now go sew a hem without puckers!

Thank you!!!!!!!! I can now hem without puckering. I tried this today and it worked perfectly.
Hey, that’s great! I’m so glad it helped. Thanks for letting me know.
Thank you so much for this site and for all of your tips. They are easy to understand and I have looked all over for how tos since I am new to sewing! Thank you for the patch tips also. I just got a new machine and folks are lining up and I havent even learned how to sew yet, lol! oh me! well, together with you, Im sure I can do this!
I’m so glad to hear that this site has helped you. Wow, you already have customers lined up! That’s great! I am sure you’ll do a great job. I f you ever have any questions, just e-mail me at thesewinggarden@gmail.com and I’ll see if I can help. You might also want to look at the posts on pricing strategies and the “Alterations” and “Sewfordough” tabs at the top of this page. Have fun!
You are the bomb. How could I not have thought of such a simple solution to hemming pants without puckers. I have a pair of my husband’s expensive dress pants in the closet dreading to have to deal with PUCKERS. Now I am sure I can hem these pants without the puckers, which means the pants I did hem with puckers I will have to redo.
Thank you “sew” much for sharing your knowledge.
So glad it helped. It won’t take you very long to redo the ones with puckers now that you have the technique! Have fun and let me know how they turn out.
You are a genius – thank you, thank you!!
I am hemming about 20 pairs of tuxedo pants for a high school men’s choir; some of the pants are REALLY long, but we can’t cut them off because they will need to be hemmed to fit other students – taller or shorter – later on.
The extra-long, tapered legs were giving me fits – but I think your solution is going to work! I didn’t even re-stitch the seam – I just opened it up so it would expand and not pucker the hem. We can always re-do the seams later if we need to.
Thanks again!
So glad to hear this helped. And, actually, you thought of an additional solution (not stitching the seams back up!). In your case, that is a perfect solution since those pants will be re-hemmed every year. By the way, how did you tame all the extra fabric at the hems?
