Thank you Luana for posting the youtube video on titanium needles. Interesting information. I sew on a Janome and purchase their needles from my dealer. His selling point was that they last longer and the Janome sews better with them. I will have to ask him if they are titanium needles. They last a fairly long time and I have them in 80/12 and 90/14. Will look in Joann's the next time I am in the store to see if they carry the titanium needles.
