I am a new sewer and at the local quilt shop where I am taking a quilting class, they told me to buy a certain brand of thread. It's Mettler 100% cotton silk-finish. They said it was the 2nd best to a thread that is twice as much and I don't want to spend $10 for a spool.
I am also taking a class at a Joanns to learn how to make pajama pants and I was wondering if the thread you use makes a difference, either for the project or the machine. Is the 100% polyester thread at Joanns just as good as the cotton stuff from the quilting shop? It's only a couple of dollars difference so I don't mind spending the extra money if it's worth it.
Also, do you buy new thread to match your fabric or just use whatever you already have that's the closest?
