It's a Universal needle. Didn't know there were Denim type needles. Oh well! I am halfway done with this project, and still using the first needle. I think I'll change this one for the second half to make sure I don't break anything. As things are, not sure I will ever need to use the thread or other 8 needles again. Only thing I would use them for is if someone else wants canvas flags or something made of denim.
I am definitely liking the BL Jazz2. It is a lot noisier than my Singer, and shakes a lot more. I am probably going to have to get a sturdier table, or just make one that doesn't shake when the BL is working. Singer doesn't even vibrate the the table I am using. I am guessing th3e Jazz2 is considered a heavy duty machine.
