The easiest way to be sure to get the right stuff the first time is to take a little piece from the blind that is broken along with you to compare. I have bought it in 15' or 30' lengths, just to keep it manageable.
You can also apparently get this stuff online, although I've not done so. Here is a link to a site with supplies for Day/Night Blind repairs and restringing:

They don't even carry the 2 mm size, but I'm pretty sure that is what I bought at the fabric store. I also see they have a video there on that page, although I have not watched this particular one.
Just from memory, a blind on most of my narrow (2-string) windows required two strings, about 7 feet in length each. The original strings were the color of the blinds (brownish, not white), but fabric store had white string. Can't tell the difference at all when installed.
