How to get lots of Minecraft leather?

Create a wheat farm, the bigger the more leather. It doesn't matter how you make it but as long as you get wheat, your good. Next, go to the location you want the farm and either build a large gated area, building, or hole. Get your wheat, find some cows nearby, and lead them into your cow farm area. Keep getting wheat and cows, then you start breeding the cows. To breed them, get two pieces of wheat and give it to two cows. Keep breeding, until you decide to slaughter them all and get their leather. If you wanted to separate smaller ones from bigger ones, make the height of the wall in either the building or hole two, then you can break a block and make a passage to another area, since the hole is one block tall only babies can fit. You can eventually make a huge farm, with both wheat and leather, and get lots of material! You could make the floor hoppers so you can make the items dropped by the cows go into a chest, and if you know how to do it, you can make the hoppers sort the raw beef and leather. You can also maybe use an auto kill method, that can use arrows or something else to kill them. Eventually, you can make a whole automatic factory that will allow you to do everything with a few button clicks. Make sure the ground is grass so the cows can eat, and there's sunlight. If you don't want it too complicated, you can just go to a plains biome and just go kill horses. Kill a ton of cows. I believe that is the only way. If you are on Xbox you can kill horses Breed cows.
