LOL! Me too!

I take it out and run it through an emery when I have to change the bobbin! I also clean out the bobbin race area at this time....

You're supposed to change them?

Oh, maybe I should next time I sit down with it. You're sure you need to change them?

i change after every quilt..

not often enough

I have to smile when people talk about changing needles. I think I probably change more often than necessary, but it can avert a lot of problems. The local repairman is also a friend and he always puts a new needle in when he works on a machine. It adds 60 cents to the bill. One lady demanded to know why he put in a new needle when she had not authorized it. She told him that there was nothing wrong with the needle that in it and anytime it was little dull her husband would sharpen it for her. She had been using the same one for 20 years. He put the old needle back in and removed the 60 cents. Don't know how many more times it could be sharpened since the tip was nearly up to the eye.:)

As soon as I hear the popping sound that tells me the needle is blunt and the changing is overdue.

I got loads with my second-hand Pfaff, so at the moment I've got the luxury of changing it for every new project. I ruined two when I tried to sew on adhesive velcro. I didn't realise it was the glue til it happened the second time-durrr! Never again!

Ok, sorry this one makes me smile too. I'm old school and always keep my machines cleared of lint. My uncle's wife told me that she had never cleaned her machine and saw no need for it. Of course, she only made dresses(same pattern) and only used polyester knits!

Probably because you never changed the needle. When you think how fast and how many times that needle penetrates fabric, it should probably changed more often than a regular sewing machine.
