Sewing Tips – Clipping Corners and Curves

Sometimes the simplest little technique can really polish off your project.
By taking an extra moment or two to finish something off right, you will start to see huge improvements in your projects.
And I’ve had a few questions on clipping corners and curves……..and why it’s necessary.
So here’s why…
It really removes bulk from the insides of seams and allows for nice and smooth curves and corners. 
 And it keeps things sharp and even.
 (And this may help those of you who wonder why you can’t get things to turn right side out without it puckering all funny.  Is that you?)
So first, clipping corners.
.
Once you have sewn 2 pieces of fabric together that have corners, you are left with this:
And if you turn it right side out without clipping those corners, you will have messy looking corners that you can’t poke out because there is too much fabric in there jamming it up.
And those corners are also very bulky and won’t lay flat for you.
But if you trim off those corners at a diagonal, cutting near the tip of the seam, but not too close……….
and then poke out the corners with something pointy……….
………you will have nice and sharp looking corners.
That lay perfectly flat.  Make more sense now?
Now how about those curves.  
Remember these instructions……..“  clip valleys, notch mountains”.  
Got it?
When you have a curve that looks like a mountain, like this:
Then you want to notch the mountain, like this:
It’s kind of like the corner method from above.  You are trying to take away some of the bulk so that it will lay flat.  So that when you turn it right side out, it will look nice and smooth, like this:
See what I mean?
And from the inside, you can see that those notches are closed up and are almost laying next to each other now because the curve forced them that way………perfect.
Now onto the valleys……which would look something like this:
And if you tried to turn a “valley curve” right side out, it would not lay flat for you at all.  It would just bunch and pucker and will fight you…….grrrrrrr.
So clip the valley like this:
So that when the curve stretches open a bit, the clips allow it to move.
And I even needed to add little notches at the top where there are slight little mountains.  See?
So then after turning it right side out, the valley lays nice and flat, like this:
If you open it up and peek inside, you can see that the little “clips” are being opened up, allowing for the nice curve of the fabric from the outside.  Make more sense now?
Now, go on and try some of these techniques (if you aren’t already) on your next project.
You will notice a huge difference in how your fabric lays and how much better the end product looks.
Yay for crisp edges.

    I have a question, not a comment…I am attempting my first vest, the pattern says to pin and clip the edge(for a curved surface like the photos), then baste, then stitch. So I am wondering that means I am clipping to allowance BEFORE I sew the sides together? Thanks for any help!

      They are saying to clip in the seam allowance, so that when you pin, and sew, your curves will be right. Sometimes the pieces will bunch while sewing if you don’t clip them first.

    wow. Thanks. I guess this is another reason to leave seam allowances…I have sometimes tried to sew 'real close' to the edge. That leaves no room for clipping.

    My favorite curve clipping tool is a pair of pinking shears……best ever, makes for every smoothly rounded curves!!

    Cyndi loves to stitch says:

    another trick for sharp 90 corners is after clipping corner, fold extra seam allowance over at corner one way, then fold the other seam allowance over it. Using your finger and thumb grab the corner and seam allowances and flip out to the outside keeping hold of the corner. corner will pop out fairly well. Onece awhile you still have to push it out a little with a blunt item, I like the backside of a small crochet hook. It's small but not so sharp as to poke a hole through the front.

    THANK YOU THANK YOU THANK YOU!!! I have been making the stuffed animals you featured a while ago and I can not get the curves to look normal… at first I thought it was my sewing job so I tried again more carefully and there were still ripples in the "valleys" especially! So I gave up. I think you just fixed my problem!!! I am going to go fix them right now!

    Your tips are so easy to understand. I was wondering if you might be able to answer a silly sewing question for me. I recently made Amy Butler's Birdie Sling and I had trouble with ironing the seams open. (in the end it came out just fine, but for next time…) I'd say my sewing level is intermediate, but I burned all my fingers and felt like there had to be an easier way. Any tip? Thanks.

    Ashley says:

    Good, I'm glad this was useful. I'll keep adding more and more tips when I can…

    Distressed Sewer – Hmmmm, I'm not sure about those vest instructions, it's hard to tell since I can't see exactly what's going on. But it seems strange to clip before sewing. (But maybe the real professionals do it that way??) So I wouldn't see any harm in basting, then sewing, then clipping and trimming. But I am known for getting ANGRY at patterns and just figuring out my own way. haha! Sometimes they make no sense to me at all! SO my advice is to switch around the order of that and do it the way that makes most sense to you. And it's all a learning process……and there really are many ways to come to the same outcome. So good luck! :)

    Debbie Cook says:

    Ashley – nice tutorial and explanation!

    Anonymous – one instance where you would clip before sewing the seam is when you are joining convex and a concave curves together, like on princess seams or a collar to a neckband, or in quilter's terms a block such as drunkard's path. The reason is because while the actual sewing lines are even and will fit together, the seam allowances are not the same length as the sewing line and you need to clip them so the SA's can open up to help the pieces fit together without puckers.

    Lily M says:

    Omg, thank you- thank you. I have steered away from tops, jackets and anything with curves because of these problems. I taught myself to sew and after making a few simple things I thought I’d have a go at a jacket. Well I bought expensive material and everything turned out well except when I got to the sleeves. That was over 5 years ago, so now I will be getting that jacket back out and trying again with my new learnt skills.
    I cannot believe it is as simple as that, other people have tried to explain it. But that shows it perfectly.

    Thanks again….
