Should I continue to sew or not ? Well some time ago I managed when changing the needle to let it fall in the machine (part below the needle where you put your bobbin). Lucky I got it out. Since then I learned my lesson and -when changing needles- I always put a piece of paper over "the hole". Same as today. But this paper had a tiny, little hole. And can you image?? yep needle straight trough and lost somewhere below. I opened the machine as far as I had to guts to do so, shaked it -first I heard the needle, now not anymore, so it is stuck somewhere-. Started to sew, so far okay. Should I leave it like this. What would you do ? Can't miss my machine. Need to sew a birthday gift.
If you are concerned by all means have your mechanic take it out. It is only a 15 minute job for them. Good luck Shirley
