I'm in the same place as you are, Rita, when it comes to needles. If I hear the popping sound as the needle goes through the fabric, I know it is time to change the needle. I'm also finding that despite what the industry says, including Superior Threads on occasion, I find some needles work better for me than others, especially with specialty threads. This afternoon, I shredded Superior metallic thread with both the topstitch and metallic needles. When I went back to a plain old jersey SUK needle, all was glorious again! This has happened before, so why did I have to go through that whole cycle again!
Because I forget???
