Sewing Machine Loose Stitches on Bottom: Causes and Solutions

Loose stitches on a sewing machine are one of the most common problems that sewers face. 

A loose stitch happens when the needle doesn’t pull the thread through the fabric completely. The fabric will look as though it’s been skipped over, or you may see little “hairs” sticking out from underneath your seam. It’s often difficult to fix this problem, but if you’re persistent and patient, you can usually find the source of the problem and fix it.

Sewing Machine Loose Stitches on Bottom

The problem can be caused by many different things, but here are some of the most common causes:

Sewing Machine Loose Stitches on Bottom

If you’re having trouble with your sewing machine top thread breaking and threading incorrectly, it could be due to a few different reasons. Here are some common causes of loose stitches on the bottom:

Brother Sewing Machine Loose Stitches on the Bottom

Brother sewing machines are designed to be easy to use and maintain, so they do not require any special care or maintenance. However, there are times when you may experience some problems with your Brother sewing machine, such as loose stitches on the bottom. 

Here are some common reasons why this might happen:

Upper Threading Is Incorrect

If you have threaded your upper threading incorrectly, then it can cause loose stitches on the bottom of the fabric. This can happen if you have not threaded the upper tension correctly or if your bobbin thread is too tight or too loose. To fix this problem, follow these steps:

Check That Bobbin Thread Is Not Wound Incorrectly

The bobbin isn’t wound properly. The bobbin is responsible for holding up all of that lovely thread you want to use for creating your project without it, there would be no way for those stitches to form. 

If the bobbin isn’t wound properly or isn’t wound at all (which can happen if your machine doesn’t have a built-in winder), then it won’t be able to hold up enough thread.

Not Using the Needle Threader Correctly

If your machine has a built-in needle threader, ensure that you are using it correctly. If you are unsure how to properly use your machine’s needle threader, watch our video on how to use a needle threader on a Brother sewing machine.

Bobbin Case Full of Fabric

If your machine has a top loading bobbin, check that the bobbin case is not full of fabric fibers. If there is any fabric in the bobbin case, remove it immediately and clean out the bobbin area before proceeding with sewing.

Check That the Upper Tension Is Correct

This is one of the most common causes of loose stitches in any type of sewing machine so always check that the upper tension is correct before starting your work on your Brother Sewing Machine. If you find any problem regarding this then change it immediately.

Check the Bobbin Was Inserted Properly

The bobbin is an essential part of a sewing machine because it holds thread inside the machine while it’s being stitched together with another piece of fabric or cloth material. 

If there’s something wrong with this part, then you may face loose stitches on the bottom.

Singer Sewing Machine Loose Stitches on the Bottom

The Singer Sewing Machine Company is a household name, and its machines are known for being durable and reliable. This makes them a common choice for home use. 

However, if you have a Singer sewing machine, you may encounter problems with the stitching coming out too loose on the bottom of your work. This can be frustrating, but there are several possible causes that you can check out to see if they apply to your situation.

The needle and thread combination is wrong

The most common reason for loose stitches is the wrong combination of needle and thread. If you are using a sewing machine with a built-in upper thread tension system, then it may be that the wrong tension has been set. If your machine has an adjustable needle holder, then it is possible that this is not being adjusted correctly. 

The needle and fabric combination is wrong

Another reason why Singer sewing machine loose stitches on the bottom can occur is that the needle type or size is not suitable for the fabric type or weight being sewn. 

If you have used a universal needle on a heavy fabric and have experienced problems, then this may be the cause of your problem. 

Singer thread tension is wrong

If your sewing machine has an adjustable upper thread tension system, then this may be incorrectly set. This can result in 

Singer sewing machine loose stitches on the bottom being pulled too tight or too loose at various points around the fabric being sewn. When this happens, it causes uneven stitching which leads to unsightly results when finished.

The bobbin is worn out

The most common cause of loose stitches is worn-out or improperly wound bobbin. The solution is to replace the bobbin with a new one.

You are using the wrong needle.

If you have used the wrong size or type of needle, it can also cause loose stitches. The solution is to use a needle that is suitable for your fabric.

The presser foot pressure is too high or too low

If your machine has a presser foot pressure setting, this may be set too high or too low for sewing through multiple layers of thick fabric. If so, adjust the setting so that it is appropriate for the thickness of the fabric.

The tension is set too tight or too loose

If your machine has adjustable tension settings, you may need to adjust these according to the thickness of the fabric being sewn and how much stretch it has also been sewn at an angle (for example, if you are sewing two layers together)

Solution for Sewing Machine Loose Stitches At The Bottom?

Tighten Your Thread Tension

Tightening or loosening the thread tension can cause loose stitches on a sewing machine. You should check this first to see if it is your issue. 

If your machine has adjustable thread tension, then try tightening or loosening it until you find a good balance of tightness and looseness in your stitches.

Check Your Needles

A bent needle may cause loose stitches on a sewing machine because it cannot properly pierce through the fabric and pick up threads from underneath to form a stitch with them. 

A bent needle will also cause skipped stitches as well as breakage of threads within the needle itself and jamming of the needle in its housing due to poor contact between the eye of the needle and guide tube shafts in relation to each other. 

Broken needles should be replaced immediately because they could damage other components within your sewing machine such as gears.

Check Your Threading

Loose stitches could be caused by threading issues. If your sewing machine has a top-loading bobbin, it’s important to make sure that the thread is being fed correctly into the bobbin case. It should also be wound evenly around the bobbin shaft.

If your machine has a front-loading bobbin like most modern machines do, then ensuring that the thread is being fed correctly into the bobbin case can be tricky because there are so many parts involved in this process. 

If you’re having trouble with this step, it might be time to take your machine into a repair shop or at least get some help from an expert seamstress or tailor who knows how these machines work inside and out.

Your Bobbin Case May Be Too Full or Too Low in the Case. 

 You will need to adjust your bobbin tension by removing some of the floss from inside of the bobbin case, or adding more floss if needed until you get a good tight stitch on both sides of the fabric.

Change Bobbin

If your bobbin is worn out or has been used for too long, it can cause loose stitches on the bottom. When you change bobbins, make sure to use the right size. 

Different brands use different sizes so make sure to check the manual or packaging for the correct size.

Use the Right

Using a wrong-sized needle can also cause loose stitching issues. Always use the right needle size for your project and make sure that they are inserted properly into their holders on both sides of the sewing machine. 

If not inserted properly, they may bend and break when trying to sew through thick fabric or multiple layers of fabric at once.

Thread the Bobbin Properly

Make sure that you’ve threaded your bobbin correctly before starting to sew anything on your machine. Many people forget about this step and just start sewing without making sure their bobbins are ready to go.

Use the Right Fabric/Needle/Fabric Combination

To get the best results from your sewing machine, you need to use the right fabric and needle combination.

The most common mistake is to use a thick fabric with a thin needle, or vice versa. This can result in broken needles and loose stitches on the bottom of your seam.
