Question about Sewing Machines

1 Answer

I am pretty new to sewing and my machine. I just changed thread and put in a new bobbin. Now my stitches look correct on the top side of the fabric but awful on the underside. There is a ton of extra thread. I have tried to re-do the threading of the bobbin, but I am not sure I am doing it right. The tension is set to auto and I am doing a straight, tight stitch. I have a singer Inspiration.

It's the tension on the top thread.  rethread the machine and make sure the thread actually goes into the tension discs.  the thread should flow with resistance.  very good explanation of the problem by the way--good luck and enjoy sewing!

Upside down stitching


Am having a difficult time picturing this. Sounds like the upper thread is creating loops under the fabric and the bobbin thread is showing on the top of the fabric.

Make sure to use a brand new needle.

Remove the thread from the machine
ALWAYS raise the presser foot and rethread the upper thread.
Make sure the thread path is correct.

Check that the bobbin is turning the correct direction in the bobbin case and the bobbin thread is threaded through the bobbin tension correctly.

Set the upper tension to the midway point (factory standard), however, this setting may need to be tweaked for your particular machine.

Bring the bobbin to the top of the project Before beginning to stitch.
How and Why to Bring up the Bobbin Thread

Retest--begin sewing slowly.

If the upper thread is still showing on the other side of the fabric, the tension is too loose. If it is pulling the bobbin thread up to the top of the fabric, the upper tension is too tight

OR the bobbin thread tension is too loose. (CAUTION: make only small adjustments to bobbin tension--1/8 of a turn at a time!!! It also helps to mark the screw groove location with magic marker on the bobbin case BEFORE making any changes so you can back it out and return to the original setting.)

Top thread covers bobbin thread makes. Stitches very thick


Remove all the thread from the machine.

Install a brand new needle.

ALWAYS RAISE the presser foot during the threading process and rethread the machine from the beginning. (Check that the upper and bobbin threads are threaded correctly in your machine.)

Set the tension dial to the midway point. This is a factory standard setting but each machine may vary.

Test your machine. The ideal tension is when the upper and bobbin threads meet in the middle of the fabric. If the upper thread is showing on the bobbin side of the fabric, the upper tension is too loose. However, if the bobbin thread is showing on the top of the fabric, the upper tension is too tight.

Tension is not static--whenever you change projects, ie fabric, thread, needle, you may need to test the tension on some scrap project fabric first. Get the tension adjusted before stitching the project.

Make sure you clean and lubricate your machine regularly to keep it operating--consult your owner's manual and use only good quality sewing machine oil (NO 3-in-1, cooking oil, WD-40, or old brown stinky sewing machine oil).

If you are still having issues, take it for service.

How to adjust the bobbin tension.


According to the manual, you should not need to adjust the bobbin tension (and I located other sites which stated the bobbin tension cannot be adjusted on this machine). Apparently, all the tension adjustment is accomplished through the upper thread::
"EN Thread Tension Upper thread tension Basic thread tension setting: "4". (1) To increase the tension, turn the dial to the next number up. To reduce the tension, turn the dial to the next number down. A. Normal thread tension for straight stitch sewing. B. Thread tension too loose for straight stitch sewing. Turn dial to higher number. C. Thread tension too tight for straight stitch sewing. Turn dial to lower number. D. Normal thread tension for zig zag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric. Lower thread tension The bobbin tension has been set correctly at the factory, so you do not need to adjust it. Please note: - Proper tension setting is important for strong seams. - There is no single tension setting appropriate for all stitch functions, thread or fabric. - A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing. - 90% of all sewing will be between "3" and "5". - For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing. - For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric. 1 A B C 22 D"

Doing further research, I found this statement on a machine review site:
"After reading reviews online from where I've bought my drop-in bobbin machines, I think many of the negative reviews are due to the bobbin thread coming up without laying across the bobbin. It can cause the stitches to look very sloppy and no amount of tension adjusting can fix the stitches."

There are several machine review sites wherein 4423 owners stated their disappointment in the 4423's performance. Some said the machine failed almost immediately and others said the machines developed problems when sewing heavy fabric.

My New Home skips stitches. I have cleaned it, changed needles, adjusted the tension and tried different bobbins .



Skipped stitches

1. The needle is not inserted correctly

Remove needle & reinsert needle( flat side towards the back of machine)

2. The needle is damaged

replace with new needle

3. The wrong size needle is being used

Choose a needle to suit the thread & fabric

4. The foot not attached correctly

Check & attach correctly

it's also possible that the machine could be slightly out of time

Thread tension


try changing the needle first--make sure the needle is the correct one for the fabric being sewed.
if you've adjusted the top tension & the bottom stitch still looks the same
it's possible that the top tension dial is needing to be checked to see if it's
working correctly

Hi, my problem is my bobbin. The tension is fine, it is when I put the bobbin into the bobbin holder. When I thread it through the plate with the top thread, it is so hard to pull out. It seems really...


TENSION: As you change projects and start sewing on different weight materials, you should test stitch on a piece of scrap material of the same weight before beginning the actual project so you can adjust your upper tension to that particular fabric. As an example, if you're changing from a denim type fabric to a silky fabric, you would definitely want to make sure the tension is correct and the stitching looks right before you start to sew the garment.

To determine whether the upper tension is too tight or too loose for the fabric you're wanting to use, try the following test. Take a small scrap of the fabric, fold it, and stitch a line ON THE BIAS of the fabric, using different colors of thread in the bobbin and on top. Grasp the bias line of stitching between the thumb and the index finger. Space the hands about 3 inches apart and pull with an even, quick force until one thread breaks. If the broken thread is the color of the thread in the needle, it means that the upper tension is too tight. If the broken thread is the color of the bobbin thread, the upper tension is too loose. If both threads break together and take more force to break, it means that the tensions are balanced.

BOBBIN: The most probable cause of the lower thread breaking is an improperly wound bobbin. Regardless of where you wind the bobbin, inside the machine, on the top of the handwheel or on the front side near the hand wheel, the basic "bobbin" rules apply.

** Always start with an empty bobbin. Never wind one color over another color.
** Don't wind the bobbin so full that it would be tight and hard to insert into the bobbin case. Most machines have an automatic "shut off" when the bobbin gets full, but if yours does not, be careful not to fill it too full.
** Wind the bobbin evenly across and in level layers.
** Never mix different sizes of thread in the bobbin and on the spool, unless you're doing sewing machine embroidery or some specialty type of sewing. Using different weights of thread on the spool and in the bobbin for general sewing will cause ragged stitches as well as other stitching problems.

NEEDLE: Probably 25% of machine repair jobs I go out on, the only problem was that the needle was put in backwards. I know you're probably saying "I've been sewing most of my life and I know how to put the needle in the machine"; however many times a seamstress will get in a hurry and not give the needle a second thought when putting a new one in the machine. If your machine will not pick up the bottom thread or skips stitches badly, in most cases it's because the needle is in wrong.

Each sewing machine requires that the "flat" side of the needle be put in a specific way - facing the front, the back, etc., depending on your particular make and model. If you have a sewing machine that takes a needle that doesn't have a flat side, you'll notice that each needle has a groove in it where the thread lays as it penetrates the fabric. Depending on whether your machine shuttle system faces to the front or to the left, the groove of the needle will also face front or left.

MACHINE THREADING: An additional area to check for stitching problems is whether the sewing machine is threaded properly. Each machine has a certain sequence for threading, and it only takes one missed step in the sequence to cause your machine to skip stitches. If you're in doubt, take the top thread completely out and start all over again.
