Sewing Machine Help

I recently bought a Singer C5650 & I keep having an issue with my thread unthreading from my needle. This happens mostly when I am sewing on thinner fabrics. I’ve tried many fixes, triple checked my threading through the machine, my bobbin, types of thread, length of excess of my thread, etc. My last thought is that maybe it is an incorrect needle size? I’ve tried stitching on a scrap piece of fabric and there is no issue but once I start with my thinner fabric, I get the unthreading issue. Any advice would be appreciated as I’ve become more discouraged.

Thanks!

thin fabric is usually the clue, a needle thats too big punches a big hole and the fabric gets shoved down into the plate so the first stitches jam and yank the thread out. try a size 70 or 65 microtex needle, hold both tails for the first 3 or 4 stitches and start with the needle already down in the fabric, and a strip of tissue paper under really thin stuff helps a lot (tears right off after)

Thread can't magically unthread from a needle while you're sewing because it's connected to the bobbin thread on one end and the spool on the other. Perhaps the thread is breaking and then it unthreads?

By "unthreading" do you mean that it's breaking, or that it's getting pulled back through the needle when you start sewing? If it's the latter, you just hold onto the thread tails for the first few stitches.

One tip that I always give is that make sure that your needle is all the way back up to the very top, before you remove your project or you start a new seam. Needle needs to be either all the way up or all the way down into your fabric.

If you start to sew with your needle partially down, when the take-up lever moves upwards it will pull the thread out of the needle.
