I'd presume that you'd have to acquire the remaining Vellum you need from a different source now.
 * Purchase from the Auction House
 * Craft at Leathercraft lv.31
 * Find another player who has the craft skill levelled and ask them to make it for you (I can do this if you're on Shiva server, but I can't imagine you'd have much trouble asking around).

Good luck!
