hey im a lvl 23 gnome lock and right now im lvling tailoring and im wondering what is the best place to farm silk cloth btw I need a lot.

Orcs in wetlands drop a lot of wool and some silk.  To really get a lot of silk you need to level up a bit.  Scarlet Monestary has been by far the best spot to loot lots of silk.  They are level 30+ elites.  It's either that or buy them on the AH.  On my server they go for 90 silver to 1 gold per stack.  If thats too much money, then try leveling, and getting groups to SM.

if u write silk cloth here in thottbot(database) it would send u to link of places that has the most drops of those... go down to where it says dropped by and click "show all" then if u click on the map links to the right it will show u exactly where by the zone the items are dropped!

stockades are a good spot to went in there and got 100pices of cloth
