This is mostly for those people who got the free version of minecraft and didnt pay Premium

Step 1: Type %appdata% into the run bar, After you go there use Winrar to open Minefrat.jar

Step 2: Go to the Mob folder and find the one called Char.png

Step 3, Find the skin you want and download it (make sure the skin is in .png)

Step 4: When you find your skin (Mine for this example video is superboy) Make a copyof it and then call it
char.png I already did it so yea.

Last step: Put the char.png into the mob folder itll appear there, then you open up Minecraft Boom
I am superboy, This works with any and all skins, If you have a problem pm me

Step 5: Optional but amazing, If you wanna change how someone looks in a texturepack while making or using one, I'll make a simple video showing you how it works.
