I buy Superior Titanium coated topstitch needles made by Organ. They stay sharp much longer then non coated. I don't have to guess or keep up with a lot of different types of needles.

The Topstitch needle is the only needle I use for FMQ. I use a 90 or 100 and have never had a problem with breaking thread since. I agree, the Superior coated needle do stay sharp longer. I test my needles for sharpness each time I use them by putting them in and out of pin cushion to make sure it doesn't pop which shows me it worn and will catch with every stitch.

Thanks for all the help! I have never used a topstitch needle but I intend to get some.
