I tried to find a Small brick of Velium but even though it's listed that she's selling it, she isn't. I see two possibilities: 1. Some came before me and bought the bricks. She might have no infinite supply. 2. The list of items is incorrect and mentions stuff that other players were selling to her. Because right now she's only selling 10 "Small Cloth" items, a Small Sewing Kit, "How to sew: Small sizes", "Velium Leatherworking", Robe Pattern and Threads in Silver, Gold and Platinum. As this is only 10 hours after today's patch I assume this should be her standard supply. :)
