Where do you get leather from on RuneScape

To get leather you can kill cows, get the hides, and tan them in a tanning shop, or you can buy leather on the GE for about 150 gp. I would recommend killing cows as it is an ok way to level up and its fairly cheep. The best place to go is the cow pen outside the gate to al'khirid and then just pay to cross the gate and tan your leather there. If your a low level use this way.
