My favorite is Schmetz top stitch needles I use for embroidery /sewing.
Changing your needle is important.
Change your needle and listen to the sound of your machine and look at the stitch quality it makes a big difference.

I do a lot of pp so use a Microtex 80/12 for piecing. Depending on the thread for fmq it changes, but usually I'll use a Topstitching needle 90/14.

I change my needle if I use different fabric, such as flannel or denim, I don't change the needle as often when I just use cotton fabrics. I have gone to using the titanium needles and REALLY like those.

change it when you feel the need! at least after every large project! if paper piecing change it more often..

here is a link to a topic I posted on the subject of needles! In it is a link that will help you learn more about them!

Was surfing last nite & found http://genertions-quilt-patterns.com

with some really good info. I printed it off for a quick & easy reference. I have no affiliation w/them but thought the info was clear & concise.

I like to use Organ titanium needles. They are sharp and strong and last about 5 times longer.

I am going to try Organ titaniums on my long arm too.

Titanium needles only have a very thin layer of titanium on the outside of the needle. If they break, they do no more or less damage than a regular needle would.
http://www.superiorthreads.com/educa...coated-needles This explains it better than I can. I use and love titanium needles. Some of them have broken in my machine for the same reason a regular needle would with no harm done to the workings of the bobbin or the shaft.

I usually break them before they get dull LOL. My "trick" is forgetting to change the presser foot when switching to zig zag and - ooops broken needle. Or going too fast and hitting a pin.

I use the titanium needles from Superior. I had signed up for the Quilters Daily Deal and was able to purchase them at 1/2 price. So I stocked up. You can usually "hear" the needle telling you to "change me". It's the pop,pop,pop, sound.

THATS EXACTLY WHAT I DO ALSO.
