So you've seen all these crafting videos, but maybe you missed how to make a crafting box, a crafting table, or a workbench. What you're going to need to do is punch some tree or, if you have an ax, use your ax and get some logs.
Put your logs here. You'll get wooden planks. Then, you put your wooden planks, you make a stick. You put them in a square, and you've got a crafting table and that is all there is to it. Go up to the crafting table, right click, and then you can make other stuff, like a chest.
