As everyone else has said, you can really make your binding whatever width you want. Making it narrower does make it a bit harder to apply, though, so I'm wondering why you want to do 2", and how much experience you have with quilting.If you haven't bound a quilt before, I would recommend 2.25 or 2.5". It will be easier to sew down, and won't make a much wider border. That being said, I did 2" on my first quilt because I didn't know any better, and it worked ok. It was more challenging, though, and as I did it I decided I would cut it wider next time.If you've bound a quilt before, your batting isn't high loft, and you aren't using flannel, then go for it - 2" is fine, especially if it gives the look you want.
