A Bluestocking Knits

Well, after twenty-five hours of knitting, I decided to block the Kid Mohair Wrap — still on the needles — and see what I've got. 

This is eighteen repeats of the "crossed eyelet" stitch, which the pattern says is what is in the accompanying photo.  If I added the knot-stitch border at the end now, my finished wrap would be only 53 inches long, so I can only assume that the "2 balls" in the pattern is a mistake for "3", as going by this test-blocking three balls of Kidsilk Haze will make it almost exactly 60 inches, the target length in the pattern.

Note that I could not reasonably get a 30-inch wide piece, so this is about 27 inches.  Pulling it harder would of course make the length even less.  It is obviously pretty fiercely blocked in the pattern's photo —

But now 60 inches seems a bit stingy for a wrap to me.  If I use the fourth ball, it would be around 80 inches, which is probably too much.  Is 70-75 inches a good length for a wrap?  I've been going through the dresser drawers, pulling out scarves and stoles and even bath towels, and draping them around my shoulders, and still can't decide.  Any advice?
