Sewing machine thread clumping up... :/ The Biscuit Farmer. 2 kids; Vagina, Russian Federation 9128 posts

I have this sewing machine, it's a Singer if that matters, and when I sew, the thread on the bottom part of the fabric always bunches up. I'll have this huge clump of thread on the bottom, but the top looks just fine. Anyone know what's going on?

Try adjusting you tension and wind a new bobbin. That one could be loose or not unwinding correct.

No lol. This is my mom's sewing machine [not that she ever uses it] but I don't know which knob that is. Looking at it... There's two that I know it isn't. There's a knob that has settings 1-4 and a series of dotted lines and as the numbers go higher, the dots get longer. And the other knob is 1 -0 and is near the needle.

Mine kept doing that too, once it was the tension and once it was cheap thread. I bought better thread and it hasnt done it yet.

Hum the one near the needle is usually the tension. I have three singers one from 2010, 1992, 1940 all of them the tension is near the needle. I have another brand a brother it is also the one near the needle. But my sister has a newer singer and hers is not the same. I think it might be a lever or something so I am not sure.



You can type in you model number and it should come up on line.

For once, a question I feel qualified to answer! :D I work in a sewing machine store where we sell Bernina, Brother, and Janome machines.



Yes, the cheap thread could be a problem. Thread does have a lifespan, and cheaper threads are made up of shorter staples (strands) twisted together. They will break and lint up your machine much more frequently. Personally, I would still with Gutterman and Mettler threads- best in the industry.



as far as your knobs go- the one with the dashed line is your stitch length. Your tension is the one above the needle. Default is usually about a 4.



Most likely your clumping is caused by something as simple as the machine not being threaded correctly. ALWAYS have your presser foot up when you thread the top, this allows the thread to go between the tension discs and not be skating on top of them. Normally, the clumping you see on the bottom is actually the TOP thread jamming underneath because it has to tension to bring it back up. I don't know if you have a top or front loading machine, but also rethread the bobbin while you are at it and make sure it is spinning the right way and also in its tensions. Also, the bobbin should be wound tightly- a squishy bobbin will ruin tension and stitch quality every time.



hope this helps...without seeing you machine, there isn't a whole lot more I can trouble shoot via forum.

It's the tension, but thank you for that information! I don't know much about sewing machines "/
