Question about Brother LS-2125 Mechanical Sewing Machine

1 Answer

Sewing straight lines...

My machine is only a couple years old, but recently it began bunching up thread on one side when I sew straight, simple lines. It seems like something between the spool of thread and the needle is loose and not keeping the thread taught, but I don't know much about how sewing machines work, so I don't know where to start to fix it. Any help is appreciated! Thanks!

When I use my Singer model 1120 for sewing straight lines, the thread bunches up underneath. What is the problem?

Be sure that the machine has been cleaned and oiled. Check to be sure the machine is threaded correctly. Check to make sure the bobbin was wound properly.

How do I set the tension on the White Sewing Machine Model 1599? I am trying to do a straight stitch but the thread is bunching up on the bottom side of the fabric.

You can download the manual from the Singer sewing machine web-site. Go to customer support/ product manuals/ and enter 1599. You'll then be able to download a pdf of the White sewing machine manual for free!

Stitches are gathering on backside when sewing on patches

This is caused by a bent needle. Try a different needle that is straight. When they get the slightest bed in them the stitching will end on the back side only

Old sewing machine, no owners manual

I got the same machine when I was 12 years old and still use it today. Try adjusting the tension - it's the know with number 0-9. To decrease tension turn it to the left. To increase tension turn it to the right.

On the side of the bobbin case is a screw that also can be turned with a small screw driver to increase or decrease tension the same way as mentioned above.

If you send an email to me at I can see about getting a copy of the manual to you. It doesn't have the cover but everything else is there.

Brother LS-2125 Upper Thread Snapping

I had the same problem and it was so frustrating! It was happening to me because I wasn't using the right size needle. Go up a couple of needle sizes and see if that helps.
