Hello, fellow sewers! Let’s talk about the coverstitch machine. It’s a wonderful tool that creates those beautiful, professional-looking hems you see on store-bought activewear and t-shirts. But sometimes, this amazing machine can be a little tricky.
Have you ever been sewing along, only to find your machine is skipping stitches? Or maybe your fabric gets wavy, or the machine struggles to go over a thick seam? It can be so frustrating. You might even feel like putting your coverstitch machine back in its box.
But please don’t! Most of these problems are easy to fix with a few simple tricks. This is your simple coverstitch machine troubleshooting guide. We’ll walk through the most common issues step-by-step, from preparing your fabric to finishing your seam. Let’s turn that frustration into a flawless finish.
Getting Ready for a Perfect Hem
Great sewing often starts before you even turn on your machine. A little bit of prep work can save you a big headache later on. It’s the secret to a smooth and easy sewing experience.
Start with a Clean, Even Edge
First, look at the edge of your fabric. Is it perfectly straight? A coverstitch machine works best when it has a clean, even edge to follow. If your edge is wavy or uneven from cutting with scissors, the machine can have a hard time feeding the fabric straight.
I find that using a rotary cutter and a mat is the best way to get a perfectly straight edge. It makes a huge difference, especially with stretchy activewear fabrics. This one small step helps your machine start off on the right foot.
Tame Bulky Seams Before You Sew
One of the biggest challenges is sewing bulky seams, like where a side seam meets the hem. Your machine can get stuck or start skipping stitches when it tries to climb that “lump” of fabric.
Luckily, there’s an easy fix for this. Before you fold up your hem, find the seam allowance. Instead of pressing it to one side, fold the two layers in opposite directions. This flattens the area, making it much easier for your presser foot to glide right over.
| The Problem | The Simple Solution | Why It Works |
|---|---|---|
| A thick, bulky side seam in your hemline. | Fold the seam allowance open in opposite directions before hemming. | This trick flattens the bulky area, creating a more even surface for the presser foot to travel over. |
You can either clip a tiny notch at the hemline to help it fold, or just use your fingers to press the seam allowances apart. This simple prep trick is a game-changer for getting even stitches over every part of your hem.
Smart Tips for Hemming with a Coverstitch
Once your fabric is ready, it’s time to start sewing. Hemming with a coverstitch can be a joy when you know a few inside tips. These hints will help you guide your project with confidence.
Holding Your Hem in Place
When you fold your hem, you need a way to hold it in place. Many people reach for pins, but pins can sometimes distort stretchy knit fabrics, creating little waves in your final seam.
A better option is to use sewing clips, like Wonder Clips. They hold the fabric firmly without leaving holes or stretching it out of shape. They are also very easy to remove just before they reach the presser foot.
Another great method is to hand baste the hem. This means using a needle and thread to make long, loose stitches by hand to hold the fold. Just be careful not to sew over your basting stitches with the machine, as they can be hard to remove later.
Where to Start Your Seam
Here is a golden rule: never start sewing directly on top of a bulky side seam. Your machine might struggle to get going, and you could end up with a messy bunch of threads or skipped stitches right at the start.
Instead, start sewing just after the side seam, on the back of your garment. This gives the machine a flat surface to begin, allowing it to form perfect stitches from the very first one. You will sew all the way around and finish by stitching over this clean starting point.
Keeping Your Stitches Straight and Even
It’s important to guide your fabric gently as you sew, but never pull it from the back. Pulling the fabric can stretch it out and cause wavy, “lettuce-edge” hems. It can also twist your seams. Let the machine’s feed dogs do the work. Your job is just to guide it straight.
If you have trouble sewing in a straight line, use a seam guide. Some machines have rulers built in, but if yours doesn’t, you can buy a magnetic seam guide. A fun little trick is to use a Lego block! Just stick it to your machine with a reusable sticky pad to create a perfect guide for your fabric edge.
The Ultimate Coverstitch Troubleshooting Guide
Even with perfect prep, you might run into a bump in the road. This is the heart of our coverstitch machine troubleshooting guide. Let’s fix skipped stitches and other common problems for good.
What to Do When You Reach a Bulky Seam
You’re sewing along, and you see a thick seam coming. What do you do? Even with the seam allowance trick, the presser foot can tilt as it tries to climb the “hill.” This tilt is a major cause of skipped stitches.
The solution is a little tool called a “hump jumper” or a height-compensation tool. It’s just a small piece of plastic with two different thicknesses. As your presser foot starts to climb the seam, you slide the hump jumper under the back of the foot to keep it level. This keeps the pressure even and helps the machine form perfect stitches.
If you’re still getting stuck, you can also try temporarily increasing your stitch length and the differential feed setting as you go over the bump. This can give the machine the extra push it needs.
| The Problem | The Quick Fix | Why It Works |
|---|---|---|
| Skipped stitches when sewing over a thick seam. | Use a “hump jumper” tool under the back of the presser foot. | This keeps the presser foot level, which ensures even pressure and helps the needles form stitches correctly. |
| The machine struggles to feed over the seam. | Briefly increase your stitch length and differential feed. | This gives the machine a little extra power to move the fabric over the bump smoothly. |
Finishing Like a Pro: How to Secure Your Seam
You’ve made it all the way around! Now, how do you finish the seam so it doesn’t unravel? This is one of the most asked questions about how to use a coverstitch. The best way is the “pull method.”
First, sew about an inch over your starting stitches to lock them in. Stop with the needles in their highest position. Lift the presser foot.
Now, gently pull the needle threads forward from under the foot. You’ll see little loops. Pull out a few inches of thread and clip them.
Finally, grab your fabric from behind the presser foot and give it a firm but gentle pull diagonally back and to the left. This magic pull will draw the top needle threads to the back of your fabric, creating a secure knot. For extra safety on items that will get a lot of stretch, like activewear, you can tie another small knot by hand on the reverse side. Trim your threads, and you’re done!
FAQs
Why is my coverstitch skipping stitches?
Your machine might skip stitches for a few reasons. You could be using the wrong type of needle. Your presser foot may be tilted when going over thick seams. A dull or damaged needle is also a very common cause.
How to stop sewing machine skipping stitches?
Always start with a fresh needle. Make sure it is the right type for your fabric. For example, use a ballpoint needle for knits. Flatten bulky seams before you sew them. Also, check that your machine is threaded correctly.
How to fix a skipped stitch?
You cannot really fix a single skipped stitch. The best solution is to use a seam ripper to remove the stitches in that area. Then, you can sew that part of the seam again. Make sure you solve the problem that caused the skip first.
What is the problem with skipped stitches?
A skipped stitch is a weak spot. It means the top and bottom threads did not lock together. This can cause your seam to pop open later. It is a big problem for stretchy clothes like activewear.
How do I stop my stitches from skipping?
First, change your needle. Second, make sure your presser foot is level. You can use a hump jumper tool to help. Third, guide your fabric gently and never pull it from behind.
You Can Master Your Coverstitch!
Your coverstitch machine is a powerful tool, and with a little knowledge, you can be the boss. You don’t need to be afraid of bulky seams or skipped stitches anymore.
Just remember to prepare your fabric, handle bumps with a level presser foot, and secure your threads with the pull method. This simple coverstitch machine troubleshooting guide will help you create beautiful, professional projects every time.
