EnderChests: Personal and Shared Ender Storage
EnderChests adds portable and placeable ender storage built around the 
Ender Pouch. The mod's crafting recipes all start from that one item, so making an Ender Pouch is the first step toward every other storage block in the mod.
Crafting the Ender Pouch
The Ender Pouch is made with a shaped recipe. You need four leathers from the `#c:leathers` tag plus one 
Eye of Ender. Arrange them in the crafting grid to produce the pouch. Because the recipe accepts anything in the leathers tag, any leather-type material that belongs to that tag works in the four leather slots.
Once you have an Ender Pouch, you can use it as the base ingredient for the mod's other two recipes.
Crafting the ender_bag
The ender_bag recipe combines a 
Blaze Powder, a 
White Wool, an 
Iron Ingot, and an Ender Pouch. Place those four ingredients in the crafting grid to get the ender_bag. This is the second of the mod's three recipes and one of the two items you can build on top of the pouch.
Crafting the ender_chest
The ender_chest recipe uses a blaze rod from the `#c:rods/blaze` tag, a White Wool, an obsidian from the `#c:obsidians` tag, and an Ender Pouch. Combine them in the crafting grid to produce the ender_chest. This is the third recipe in the mod.
Notice that the ender_chest recipe calls for a blaze rod from the rod tag rather than Blaze Powder, and obsidian from the obsidian tag rather than a plain block. The ender_bag recipe instead uses Blaze Powder directly. Keep the two recipes separate in your head so you do not mix up their ingredients.
What the recipes share
All three recipes are connected through the Ender Pouch. You cannot craft the ender_bag or the ender_chest without first crafting an Ender Pouch, since the pouch appears in both recipes. That makes the Eye of Ender and the four leathers the true starting point for the whole mod.
Both the ender_bag and the ender_chest also require a White Wool. If you plan to craft both, gather at least two White Wool so you do not have to stop partway through.
The two advanced recipes differ in their other ingredients:
- The ender_bag needs Blaze Powder and an Iron Ingot.
- The ender_chest needs a blaze rod from the `#c:rods/blaze` tag and obsidian from the `#c:obsidians` tag.
Planning your materials
Work backward from what you want. If you only need the Ender Pouch, gather four leathers and one Eye of Ender. If you want the ender_bag, add a Blaze Powder, a White Wool, and an Iron Ingot on top of the pouch materials. If you want the ender_chest, add a blaze rod from the `#c:rods/blaze` tag, a White Wool, and obsidian from the `#c:obsidians` tag instead.
Because the tag-based ingredients accept any item in their tag, you have some flexibility in which specific leather, blaze rod, or obsidian you bring. The Eye of Ender, Blaze Powder, White Wool, and Iron Ingot are named directly, so those must be the exact items.
Summary
Three recipes define the mod: the Ender Pouch from four leathers and an Eye of Ender, the ender_bag from Blaze Powder, White Wool, Iron Ingot, and an Ender Pouch, and the ender_chest from a blaze rod, White Wool, obsidian, and an Ender Pouch. Craft the Ender Pouch first, then decide whether you want the bag, the chest, or both, and gather the extra ingredients accordingly.
