Just keep in mind that Felcloth is a pretty rare drop: I think around a 5% drop rate. Luckily, there are many more Satyrs than, say, elementals (who have a 5% drop rate on Essences, but it takes forever because there's so few and people kill them so much!).
It takes a while; I just bought it from the AH to make Mooncloth, and I used Runecloth Bags to level to 300. My guild was happy about the reduced prices, hehe :-P
