I change mine when it starts makeing a clacking noise or when I break it.

Depending on the projects I have been sewing, I probably most of the time change my needle about every 10-12 hours of sewing...that really is a lot of sewing...and if there are any signs of problems I will change it sooner...such as skipped stitches, any noises such as a thump, or any other problems with stitching. Quilting through layers of fabric will dull a needle faster than piecing, and sewing through fabrics other than cottons also will dull the needles faster. Really shouldn't wait until you break a needle to change it.

I have heard that, glad to know what it is. Lol

You may actually throw your timing off on your machine by doing that.

I don't change mine as often as I should, however I "feel" it when the needle goes dull. The machine sounds differently and the seams aren't as smooth.

I change mine when the needle makes a little pop as it sews(like someone already mentioned) if I haven't broken or bent it first. If it is just dull, I save it for sewing on my treadle. My treadle doesn't really care how old the needle is. As long as it can get through the fabric, it will sew.

popping sound , stitch quality, etc.

I heard the pop today...so thats what that means. Thanks!

I only change the needle if I'm having a problem w/ missed stitches or whatnot. Or, if I need a specialty needle. For regular piecing, I have found that since I put a titanium needle into one of my machines, I haven't had to change it, and I put it in around last December!!

when you start getting uneven or skipped stitches it usually means you needle is dull- and time for a change- or if it gets a burr- or bends...recommendations are with each new project - or 8 hours of sewing- but if you are trying to (stretch the usage) to the limit- when your stitch quality is no longer what it should be

I have a system for cleaning my machine and changing my needle. I have my bobbins in a case and only have 5 bobbins wound at a time. When the 5th is used I clean my machine and then get 5 more wound after it is cleaned.

At this point I put my needles in the tray beside the 5 bobbins, which lets me know that once those 5 are used I not only clean my machine, but change my needle.

So, clean after 5 bobbins and change needle after 10. You don't think it makes a difference, but it REALLY does (sort of like when you change your rotary cutter blade and are in awe at how easily it cuts through fabric after the change).
