I think it's the Tara Sha
wl With the 10½s you probably got 3 sts/inch, but you'll probably get about 2 sts/inch with the 17s. So that would make it 30" wide, not 20" if you use 60 sts for a cast on; the length is 60" no matter what. If you keep the 60 sts, it would come out about half again as large (per sq inch) so it would take 6 skeins. You could make the CO about 40 or 42 sts and it should be about the same size and use the same amount of yarn.
