I have trouble with a metallic thread. Superior Threads japanese brand wt40. Upper thread already set to no 1 tightness. Machine is Singer Legacy Any suggestion appreciated.
What kind of needle are you using? On what fabric, and what’s on the bobbin?
Needle is a generic singer 75, the bobbin has polyester thread below. Tried it with different fabrics, same result. Somehow the thread is not grabbed when the needle goes down.
I would advise to try with a thicker top-stitch needle, since metallic threads are thicker and stiffer. The 75 is very thin, you might have to try 90 or more if your fabric allows (or test on other fabric first). The top-stitch needles have a wider eye so the thread can glide through better (topstitching is often done with thicker decorative thread). Also make sure that the thread unwinds without snagging ot curling. And go fairly slow.
Thank you i will try.
