Frankly, I'm overwhelmed by thread choices. I usually used Coats and Clark. I bought some thread on sale at HL that was super linty, and then I understood what people were talking about when describing their thread as linty! I did not want to get my new sit down long arm all dirty with lint! I like Gutterman thread. I was given 4 white cones that have lasted forever. I enjoy using the cones of thread, but I don't want to purchase one that is linty. I definitely don't know enough about thread to use different threads for different jobs.
