I was at a LQS over the weekend. An instructor was teaching a class, and I overheard her say "And be sure to buy new thread every time you begin a project." One of the students said she has thread from a sewing project from last year, and the instructor told her to go into the store and buy new thread. Really? Thread doesn't last a year? I have orange thread from a Halloween project I made two years ago. In fact, I probably have thread from three years ago. Should I toss them out? Or, was this instructor trying to help the LQS by throwing a little extra business their way? How do we know if the thread at the LQS is more than a year old?
Sorry if these are dumb questions, but hearing what that instructor said really bothered me.
