Can I help with that? I can use the math behind the relationship between the number of yards, and the width of the knitting needles, to figure it out.

Okay so how much yarn would I need for the sweater if I use size 8 needles (U.S. sizing)
user
Assuming that the sweater will be made using a stockinette stitch, and that it's 42 inches wide, a rough estimate for the yarn required can be made by multiplying the length by the number of rows.  42 times 8 is 320, so using size 8 needles, you should use about 320 yards of yarn.  You might want to try a different type of stitch though, since stockinette is a relatively slow stitch, and you'll probably need to knit for a while.

Do you know how many skeins of yarn that would be?
