I use 2" all the time (because I also run into that problem of not quite enough fabric). I sew it on using a bit skimpier of a seam.
I probably only sew it about 1/16th inch less, so it's right on the side of my foot instead of a bit over. I sew a few inches and then turn it to see if it's going to work, and adjust as needed. I don't unsew the "bad" part (if there is one) from starting wrong until I get all the way around and back to the beginning.
