Hi, Miss Purl! Do you have any idea why my sewing machine snaps the top thread every half inch? Ive changed needles, thread, and tension. I’m going to punt it through the window.

Hi, Lissla! Good luck with the labor thing – have you resorted to jumping jacks or running up and down stairs yet?
There’s so many reasons your top thread might be snapping. In no particular order:
– The thread itself might be weak. If it was left on a windowsill in the sunlight or had needles stuck into the thread on the spool or it’s old or it’s faulty – those are all things that can weaken thread. Try switching to a different spool that you know is good.
– The bobbin tension might be too tight, and pulling too much on the top thread. When the bobbin is threaded, you should be able to hold it by the tail of the thread, snap your wrist, and have the bobbin fall 4-8 inches comfortably before it stops. If it keeps going, it’s too loose. If it stops too soon, it’s too tight. Both the bobbin and top tension need to be adjusted as you use the machine.
– You might be using too heavy or too fine of a needle for the thread or fabric. What are you using and what are you sewing? Or there might be a burr on the inside of the needle that’s rubbing on the thread. Or it might be the fabric itself – I was sewing with some acetate taffeta once, and that snapped thread like no other.
– The thing nobody wants to hear: There might be something wrong with the timing of your machine, so you’ll need to take it in to be tinkered with by a professional. Sewing machines, like cars, need tune-ups every once and a while.
Before you take it anywhere, though, blow all the dust out of it, oil it, and check the tension on both the bobbin and the top thread. Treat it like a lady.
How is it snapping? Does the thread wad up on the fabric before it does? Does it just break?
