This can even use things like book and quills and maps! Using the amazing MCEdit, you can!
1.Make the item you want, then put it in a chest.
2.Close the world and hop in to MCEdit.
3.Find the chest (Note: It looks like stone for some reason.) and double click on it. A GUI will pop up.
4.You should see the item(s) near the top of the GUI.
5.Click on it, then go to the amount box. Type in -1. You're all set!
Five easy steps to make an infinite item. If you put it in a chest and hook it up to a hopper, It'll suck hundreds of the item out. Put it into a dispenser with a button, and you get infinite items! Yay!
