When sewing a curved seam, you are supposed to be clipping or notching the seam allowance, so that the seam can stay flat and smooth. The rule is that when the seam is concave, you clip the seam allowance; when the seam is convex, you notch the seam allowance. This is an important step.
What is the difference between clipping and notching?
Unlike clipping, which allows fabric to spread out, notching enables it to come closer together without the bulk, by removing the excess fabric. So it will now lie neat and flat without any bunching, like the last photo above! Does that make sense? Do you have any of your own tips and tricks when it comes to curved edges?
How do you use clipping clipping?
Clipping is most often used on necklines to make them lie flat. (I clipped the neckline of this tencel woven tee.) When you have an inside curve, meaning the curve goes into the main area of the fabric, you will need to clip.
What is notching and how do I do it?
Notching helps us to get rid of this unwanted excess. To notch your convex seam, snip little triangles out of the seam allowance every 1/2" or so. Get nice and close to your stitches, without snipping right through them of course. Turn your seam out to the right side, give it a good press and revel in that lovely un-bunchy flatness!
Is it clipping or notching when sewing curved seams?
Clipping or Notching? That is the Question. When sewing a curved seam, you are supposed to be clipping or notching the seam allowance, so that the seam can stay flat and smooth. The rule is that when the seam is concave, you clip the seam allowance; when the seam is convex, you notch the seam allowance. This is an important step.
What is notching and clipping?
Notching is similar to clipping, but instead of taking a single snip out of the fabric, you cut out a small amount of fabric. Notching is used on convex curves and exterior corners because the seam allowance is larger than the space it will be turned into.
What is the purpose of notches?
Sewing notches are the little triangles or markings on your sewing pattern that help you match up your pieces. They may seem a pain when you are cutting your fabric out but they stop you joining pieces upside down or back to front and having to spend a frustrating time with your seam ripper later on.
Why is clipping important in sewing?
Clipping is very good on concave curves as it allows the fabric to 'stretch' apart. Cutting so close to the stitching can be a bit nerve racking, but the stitching will stop the fabric from tearing any further, provided you have not cut through the stitching.
Why is it important to cut and use your notches?
Pattern notches are small marks made on the pattern to ensure that one pattern piece will match up to the pattern next to it. They can be used to show what the value of the seam allowance is, and can also be used as markers along a seam to make sure that the two pieces of fabric will come together correctly when sewn.

What does it mean to clip curves in sewing?
Clipping the excess around a curve eliminates the bulk and creates a smooth outer edge while maintaining the curved shape. In garment sewing, the curve around a neckline is an inward curve. If you measure the length of the seam compared to the length of the curve, you'll discover the seam is longer.
Where do you put notches?
Put notches in the same places on the back pattern piece, so that when you join the pieces, the notches will match. For example, when putting a notch on the side seam of the back pattern piece, I will put it in the same position as the front - which is at the top of the seam.

When cutting the materials this is how the notches should be cut from the seam allowance?
Notches are always cut into the edge of the fabric, never the middle of a piece, and they may not be deeper than the seam allowance. On some pieces, double notches – two notches next to each other – are also used to make lining the piece up easier.
What is clipping on a curve?
Clipping is done on concave curves. Think inward, sunken in, bowl, or valley. These type of edges would include necklines, armholes, etc. For concave curves, you simply clip, or snip, into the seam allowance at a vertical angle to the stitching.
Why do you clip seam allowances?
Clipping like this will allow the seam allowance to spread / fan out, giving it the necessary movement to conform to the right shape when it’s turned right side out. See the last photo above? Look how nice and flat and neat it looks! No twisting and pulling!
How to clip a concave curve?
For concave curves, you simply clip, or snip, into the seam allowance at a vertical angle to the stitching. You want to get as close to the stitching as possible, without actually clipping through it. Do this about every 1/2” or so. Too much clipping can weaken the fabric, but not enough won’t provide the necessary movement.
Why doesn't my seam lay right?
When you work with curved seams, you can either end up with excess bulk or a lot of pulling and tugging. This is because the length of your stitch line measures differently from the length of the edge of your fabric. So when it is turned right side out, it doesn’t conform correctly or lie flat. You can solve this by either clipping or notching your seam allowance, to allow for that adjustment.
Does clipping fabric weaken it?
Too much clipping can weaken the fabric, but not enough won’t provide the necessary movement. Clipping like this will allow the seam allowance to spread / fan out, giving it the necessary movement to conform to the right shape when it’s turned right side out.
How to clip a curve?
Use the tip of your scissors to clip at even intervals along the curve, being careful not to cut into the stitch line.
Why is my curve lumpy?
An outward (convex) curve will appear lumpy if you do not reduce the bulk of the seam allowance. In fact, you might not even be able to turn it to the right side.
What happens when you turn a seam right side out?
When a seam is curved, turning the fabric right side out can cause pulling or wrinkling. To make curved seams flat, use the tips of your shears to notch or clip the seam allowance, taking care not to cut into the stitching.
Does clipping help with a smooth neckline?
Clipping will also help keep the neckline smooth on the Kenedy dress for a smooth curve.
Grading
When you grade a seam allowance you are cutting each layer of the seam allowance down slightly to reduce bulk in the finished project. When grading, you cut parallel to the stitching line. This series of cuts creates “stair steps” which will help to prevent an unsightly ridge that may show through on the finished product.
Clipping
When you clip a seam allowance, you make a series of small cuts perpendicular to the edge of the fabric. When you have a concave curve or an interior corner which needs to be turned right side out, you will need to clip to release the tension of the seam allowance.
Notching
Notching is similar to clipping, but instead of taking a single snip out of the fabric, you cut out a small amount of fabric. Notching is used on convex curves and exterior corners because the seam allowance is larger than the space it will be turned into. Since notching removes small amounts of fabric, it will reduce bulk in the finished product.
How to notch a convex seam?
To notch your convex seam, snip little triangles out of the seam allowance every 1/2" or so. Get nice and close to your stitches, without snipping right through them of course.

What happens if you turn a convex seam out?
Again, if you try to turn your convex seam out to the right side pre-notching, you'll find that the excess seam allowance bunches up as the curve of the raw edge is longer than that of the seam. Notching helps us to get rid of this unwanted excess.
How to get tension out of seam allowance?
By simply snipping, or clipping, into the seam allowance getting nice and close to your line of stitching - but not too close! - you will release the tension and find that pressing your seam out to the right side is now easy as pie.
Where do you find concave seams?
This type of seam would most likely be found on a neckline or a curved side slant pocket. Once you've sewn your concave seam, have a go at turning it to the right side and getting it to lie flat. It won't.
Do you clip or notch curves?
You will get a far superior result if you trim curves back to an 1/8th inch and do not clip or notch. The result will be truly smooth curves without ANY angles and a cleaner result without lumps and bumps from clipping and notching showing. If you still feel the urge to clip or notch then I agree with Linda and stagger them.
Can you make a curved seam crisp?
More often than not, it's smallest details that make the biggest difference to the finish of your handmakes. But knowing what technique to apply, and when, and why, can sometimes baffle even a seasoned seamstress. If sewing a curved seam was already tricky enough, then getting it to sit perfectly crisp once it's pressed can prove to be even more frustrating... Unless you know when to clip and when to notch.
When to use clipping?
Clipping is most often used on necklines to make them lie flat. (I clipped the neckline of this tencel woven tee.) When you have an inside curve, meaning the curve goes into the main area of the fabric, you will need to clip. First you cut out your project and sew the seam allowance.

The rule is that when the seam is concave, you clip the seam allowance; when the seam is convex, you notch the seam allowance. This is an important step.
What happens if you don't clip seam allowance?
By the way, if you do not clip or do not notch that seam allowance, the excess fabric of the seam allowance will bulge up like an eyesore. Now let’s look at the seam allowance of another type of curve. This one looks different. There are two layers here, and I stitch them right sides together along the curve.
Why is the seam allowance wavy?
However, if I decide to press the seam open, the unclipped and un-notched side of the seam allowance is now wavy due to the excess fabric.
Does the concave/convex rule work?
So in this scenario, the concave/convex guideline doesn’t even work. However, if you look at it as allocating space for the seam allowance, then it works. The reality is that after a while, you are not going to think about this exercise as allocating space for the seam allowance or using the concave/convex rule.
Why is it important to cut as close as possible to the seam?
Why is it so important to cut as close as possible to the seam? In the case of outer corners, the seam allowances get turned into a smaller space. In the case of inner corners, the seam allowances get turned into a larger space. Which seems like it would be better, but it isn’t because the seam allowances need to make the curve around the corner, but they aren’t long enough to do it. As a result, the fabric bunches up in a terrible way if you don’t cut into the corners.
What happens if you don't cut into the seam allowance of inner corners?
If you don’t cut into the seam allowance of inner corners, the fabric won’t even lay flat once it’s turned.
Why do you need to turn the seam allowances right side out?
Why do you need to do this? Remember that, upon turning the fabric right side out, the seam allowances will end up on the inside. However there is less space inside a corner, so the seam allowance around the corner would end up all bunched up inside the corner. As a result, the corner will not lay as flat and will be excessively bulky.
What does it mean when you pin fabric together?
Pin them together, right sides facing. (This is an expression used constantly in sewing instructions. It means that the right sides of the fabric pieces are touching on the inside, while the wrong sides are on the outside.) This may seem odd at first, but don’t worry– the right side will face out in the end.
What to do if you accidentally cut into a stitch?
If you do accidentally cut into the stitching, go back and sew just outside the previous stitches, away from the cut.
What to do if your corner doesn't lay flat?
If you find that your corner won’t lay flat after turning it, turn it back inside out and cut a little bit closer to the seam. The same principles apply to curves.
Do you have to have one line of visible stitches?
You will now have one line of visible stitches running parallel to the first line of stitches hidden inside the fabric fold. Here I’ve used the same stitch length for the original stitching and the topstitching, but frequently a longer stitch length is used for topstitching. Congratulations!
