Welcome, from Pennsylvania. Yes, rethread your machine, both top and bobbin. And make sure you put in a new needle with each new project. If you are sewing on synthetics, polyester batting etc. the needles dull much faster than with all cottons. Also make sure you are using the right needle for the purpose. There are quilting needles, embroidery needles, and other kinds too as well as needles sizes. I use a 80/12 for all purpose sewing. As experienced as I am at sewing, I sometimes forget to check that the thread is over the thread takeup hook.
