Damn Typo

Working on a Shawl from "Folk Shawls Today (?)" Pattern has a 308 cast-on. On the increase row, to 330 stitches, pattern said knit 18 stitches, kfb, knit 12, kfb..... knit 17 stitches. When I got to end of row I only had 16 stitches. Had to take the whole row out. Should have been knit 17, kfb.... Sorry, just needed to rant. Later
