I’ve never taken a poll, but I’m willing to bet that most sewists would choose a seam ripper as her favorite, must-have sewing tool. However a surprising number of people who sew don’t know to how to use a seam ripper correctly or at all!

It’s pretty much impossible to complete a sewing project without using a seam ripper (also known as a stitch ripper, unpicker, or stitch unpicker). They are absolutely essential for pulling out mistake stitches.

There are a lot of different styles of seam ripper, but my favorite is this small ergonomic seam ripper by Dritz*. There is also a large ergonomic seam ripper* that is exactly the same, but bigger. Below there are another two types of seam rippers: one with a special “seam eraser”* and another seam ripper with a magnifier and light*, which is good for people with bad eyesight. (I haven’t actually used them myself, but if you have, I’d love to hear about your experience!)
Whatever shape it is, all seam rippers have the same main structure: a handle with a metal tip. The tip has a blade between a point and a little red ball.

Most people know how to use a seam ripper to tear out individual stitches, but a lot of people have no idea why there’s that little ball on the unpicker.
Well, I’m here to tell you that that little ball lets you rip out stitches very quickly. And I’m going to let you in on the trick! Watch this short video or continue reading below to find out how to use a seam ripper correctly!

How to use a seam ripper for individual stitches
First, let’s prepare a practice piece. Cut two fabric rectangles and sew them together, right sides facing, on at least one long side. Turn the fabric right side out and iron the seam/s flat.

- Hold the fabric with the seam facing you.

2. Gently pull on the fabric until you can see the stitches. (Normally you would use a color that matches the fabric. I used black to help it show up more.)

3. Stick the pointed tip under a stitch that needs to be removed. The first stitch is always the hardest one to pick out, so be careful that you are catching only the thread and that you don’t poke through the fabric.

4. Push the seam ripper gently so that the stitch reaches the blade in the curve (to the left above), and push a little more so that the blade cuts right through the thread (to the right above).

5. Continue this way for any other stitches that need pulling out.
This method is perfect if you only have a few stitches to tear out, if the seam is curved, or if the fabric has a long nap. If, however, you have a long straight seam that needs to be removed, the following trick will save you a LOT of time!
How to use a seam ripper for rows of stitches

- Start by pulling out a few stitches, as described above, at one end of the seam.

2. Now insert the ball between the two layers of fabric with the blade against the stitches.

3. Hold the fabric with your left hand and the seam ripper with your right (or vice versa if you are a leftie). Pull the fabric a little towards you (or just hold it still) while you push the seam ripper a little away from you (in the direction of the arrow above and to the left).
The blade will cut right through the whole line of stitches, gathering them up (the little tangle of black thread shown by the arrow above and to the right). The ball slides easily against the fabric without cutting or poking into it.

It takes literally just a few seconds to rip out a whole long line of stitches this way. What an amazing time saver!
But I’m not done, because there’s still one more super useful way to use a seam ripper:
How to use a seam ripper for buttonholes

Seam rippers are very useful for opening buttonholes, too. Here’s how:
- Sew a buttonhole either by hand or by machine.
- Stick a straight pin at each end of the stitches, but on the inside of the bar tacks (those longer stitches at the top and bottom).
- Stick the pointy end of the seam ripper into the fabric between the columns of zigzag stitches and push it through in each direction until it hits the pins.
- Remove the pins, and your buttonhole is open!
Find more about this use of a stitch ripper in my lesson on how to sew a buttonhole with a sewing machine.

As you can see, the seam ripper is incredibly useful because it allows you to remove mistake stitches and save your sewing projects! It is also indispensable when sewing buttonholes.

Great tip , thank you for sharing!
Hope you find it useful, Maureen!
Lisa, I have been sewing a LONG time and I didn’t know you could use both blades. Thank you, thank you!!! This is going to speed up fixing mistakes. Showcased today…
I was shocked when I learned this (with years of sewing experience under my belt), and even more shocked to find out that I was far from being the only one who didn’t know this! I’m so glad to hear that this will be helpful for you, Pam! <3
Thank you so much for this tutorial on how to use a seam ripper to take out a whole seam. I always wondered what the little ball was for. It certainly makes taking out a seam a breeze.
So glad that it was useful for you, Gail! It really does make things easier… at least on straight seams!
I had no idea how to use the ball end of the seam ripper either…after 50+ years of sewing. Thank you! Now, can you tell me if there’s an easy way to remove surged edges or seams? I tend to shy away from altering or upcycling clothing that has lots of surged seams and would like to know if there’s a quick way to remove them 🙂
Oh, I also have the terror of having to pick out serger stitches! This video (https://www.youtube.com/watch?v=jSMP-7_LmIU) shows the way that I’ve always heard of doing it, but who knows… maybe there’s another trick out there somewhere! That would make me a happy sewist for sure!!
Thank you! That was helpful 🙂
Glad to hear it!
Holy moly, I’ve been sewing for 60 years and never heard this before! Thank you so much for this post!
Sew on and sew forth!
Haha! That’s so funny! Thankfully, we never stop learning and there are always more cool things for us to find out, right?!
Any tips for using this method on knit or swim fabric? I still end up cutting into the fabric, maybe due to the stretching, which makes the ripper not stay in a straight line?
Yes, I think you’re right, that the stretchiness means that the fabric won’t stay in place, so the seam ripper can cut into the fabric as it moves around. I might just go stitch by stitch, rather than ripping out whole lines quickly.
Hi and thank you for this great tip! At age 71 I am a new sewist and I know I have a lot to learn. I started trying to use my sewing machine earlier this year and realized that I needed a machine that didn’t have to use a foot pedal because of my neuropathy (the same reason I quit driving a car). As I was trying to teach myself to sew, I became great friends with my seam ripper. I need one with a larger handle because it is harder to grip it. Thank you for teaching even old ladies how to sew!
~~kay~~
Hi Kay! I actually lost my seam ripper that you can see in this post and accidentally purchased the larger version of it, and I have to say that it’s quite comfortable to use! What have you done about the sewing machine? Mine has a button which allows you to sew without a pedal, but I don’t love using it because I feel like it doesn’t give me enough control.
Lisa, I find that I have greater control with the button for sewing and partly because I have that lever than can make the machine go faster or slower.
~~kay~~
Oh yes, mine does too, thankfully!
Omg your a lifesaver! I thought of using it that way before and hadn’t ever actually done it( just started sewing about 2yrs ago now ). Anyway, I thought maybe it’d be easy, now that I’ve seen this… it definitely is and a whole lot faster! So thank you, I’m so glad I saw this! Looking forward to more tips and tutorials from you! Your my new favorite xoxoxo
Yay! I’m so glad to hear that this helped you so much! It really is super useful, especially with long, straight stitches. Have fun!
Can I use a seam ripper to remove embroidery from the shirt? I am just curious to know if it is good to use Seam Ripper other than a Razer.
Sure, Maria, I don’t see why not! But don’t use this trick, going quickly. Pick out one stitch at a time.
