So, I'll show you how to get your head like I said. So first, give yourself a command block, /give @p command_block. Then, you're going to put in the command, /give @p minecraft:skull 1 3 {SkullOwner:"YourUsername"} . So, last you should get your head. But pay attention to the command where it says YourUsername. That is when you put in your username, like it says. Or you can put in somebody elses username to get their head. But yeah that's pretty much it for this, so hope you enjoyed!
