I have a lot of needles in my drawer (most of them 80/20s) and I plan to use them up. They are used both for piecing and for quilting, I probably don't change my needle soon enough but my machine lets me know when it is time (the sound and feel changes) When they are used up I plan to replace my needles with topstitch needles. According to the expert at Superior thread, it is a better choice. I will invest in different sizes because I plan to use different weight thread.
