Sholazar Basin Frostweave Cloth Farm (WoTLK - Mists of Pandaria)

This is one of the best locations for players to farm for straight up Frostweave Cloth. The Undead around Freya have almost an instant respawn time and are very easy for you to kill. You won't have to worry about moving around too much in this area either since the mobs don't spawn very far apart at all. Also since they respawn instantly, over crowding isn't much of a problem either.

If someone does happen to arrive, the beach is the best area to farm for the cloth, in this small area. Hold your ground and force them to the other side of the area, since you where there first. Also as a side note, if one of the Ravagers is getting beat up too much by the flowers, ignore him. If you waste your time attacking him, he won't drop loot since he has taken too much damage from another source.
