Remove the thread from the machine.
Raise the presser foot.
Turn the handwheel until the take-up lever is at it's highest position.
Set the upper tension to 5.
Re-thread the machine.

Top stich is normal, bottom stitch is loose


Tighten up the top tension so it will pull the bobbin thread up. The top and bobbin threads should meet in the middle of the fabric.

Singer Sewmate, the zig zag stitch is perfect on the bottom of the fabric, but lopsided on the top, how do I fix this?


This could be a combination of two things, to much down pressure on the spring loaded foot on top or the fabric distorting it, the other is a top stich tension issue adjust tension in and out to see if this improves the stich.
good luck

My stiches are loose on the bottom of my banner - is it the bobbin or a tension issue?


If the threads on the back are loopy, you need to tighten the top tension. If you have a spare piece you may want to run some of the plastic through the machine until you get the tension correct. If the top tension is too loose, the stitching will just pull out.

Top stich perfict but bottom stich too loose on vivo singer machine 1004


Your bobbin tension needs adjusting, and although it is not hard to do and doesn't require that you take the machine apart, you MUST do it systematically. If you don't, you'll make things worse.

First, download the user's manual from the Singer site if you don't have one. On page 20, you'll see a discussion regarding tensions, and what improper tension looks like. Tension is a balance between the top and bobbin.

Then, using scrap fabric, set your top tension on Auto and make sure your needle is all the way up in the clamp. Run a line of straight stitches, and next to it, run a line of zigzag stitches, maybe four inches, and examine it. The illustration on that page will show you what your straight stitches SHOULD look like. If your zigzag stitches show one side that looks like "chicken tracks" but the other side looks like it should, the chicken tracks side is too tight. In your case, if the bobbin is too loose, the top will look like chicken tracks. It helps a lot to use two different thread colors, as well as a third for the fabric.

To adjust the bobbin tension, you will need a tiny straight blade screwdriver. If you have an indication that the bobbin side stitches are too loose, take the bobbin case out of the machine and locate two screws on the side. One is a Phillips--don't touch it. The one on the left of the Phillips is a straight-slot screw--that's the one you want. The saying is "lefty loosey, righty tighty." If your test indicates the bobbin tension is indeed too loose (which can happen over time), you need to tighten it by turning the screw 1/4 (ONLY) turn to the right (righty-tighty). Test again. You should see at least some improvement to indicate you're on the right track, and repeat--turning ONLY 1/4 turn--until your top and bottom tension are balanced. Don't forget to also test with a zigzag; I have adjusted bobbin tensions in the past that looked OK on the straight stitch, but the zigzag indicated I wasn't quite there yet.

My top stich is tight,but bottom is loose of my singer sewing machine.


Think in opposites... the top stitch is formed by the bottom thread tension and the bottom of the stitch by the top. So either the bobbin thread is too tight or the top thread is too loose. Check the bobbin thread first as that is the one most overlook. It should come out of the bobbin without having to yank it hard but it should have a little resistance.

Top stitche is to tight and bottom stitche is to loose


Meaning you have adjusted the tension for the top thread as well as the bobbin?

Use two distinct colors of thread - one for the top and one for the bottom.

Thread the machine with the presser foot up.

The two threads should meet in the middle of the stitch with neither obvious on the opposite side of the seam.

Set the top thread tension to 4 and adjust the bobbin as needed.

This is the general rule of thumb.
Loops on the bottom, problem is on the top. Loops on the top, problem is on the bottom.

This is what you should try.. First of all, unthread the machine and start over. Just before threading the needle, put your presser foot down. If the thread pulls thru easily, it is not thru the tension wheel right. If you cannot pull the thread thru, thread the needle and try a few stitches.

Singer 221-1 stitching is good on bottom but not on top


pucker is caused by too loose or, to tight adjustment of: the thread tensioners both the bobbin tensioner and, the needle tensioner need to be adjusted: to adjust the needle tensioner turn the side knob clockwise is tighter counterclockwise loosens; the bobbin tensioner is a tiny screw on the bobbin holder adjust both tensioners until your stich loops' both top and, bottom are tight but, the machine does not break the thread
