To make a crafting recipe you need 4 of any of the following items:
- Cow fur
- Creeper fur
Sheep fur and pig fur don't work; they can only be used for creating leather.
Then you need to create a blank recipe scroll by putting a piece of paper or leather in a crafting bench. After this you need to place the 4 of your items around the scroll like in the picture to get your crafting block for that piece of armour (you dont need 2 at the top, I accidently placed 2). To create weapon recipe scrolls its a similar idea but instead of using fur or leather you need to use:
And arrange them like above, replacing the leather.
