Thank you all!! Bree123 - yes, my thread looks like that. I was given 1 of the spools of thread, needed a 2nd one for a current project. Researched, and felt I was buying the same thread color. But then I noticed the 1LQ and 1NQ on the labels and thought - oh no!! Yet they look the same (but I know something can look like something else but then when you use it you find it really isn't the same).
It is sounding like 2000 is really the thread color then. If it's a different color, then it will be a different number. I really like the Aurifil thread! So much less lint that other threads I have used.
