A Birch trap door is a solid and transparent block that can be used as an openable barrier.
To make Birch Trap Door, you just need two things, Birch Wood and Birch Wood Planks. Please follow the following steps to make Birch Trapdoor.
In order to make a Birch Trap Door, the basic item you will need is birch wood block. Find a Birch tree and use your Iron Axe to cut down at least two Birch logs.
Birch Wood Planks
After that you will need to craft birch wood planks. Make your way to the crafting table and add Birch wood blocks at the center of the 3*3 crafting grid. You will get 8 birch planks from 2 birch blocks in the right-side box of the crafting table. Add these wooden planks into your inventory.
Now craft the required item using the crafting table. Add three Birch wood planks in the second row and three planks in the third row or you can choose any two rows of your choice to add birch wood planks. This will craft Birch trapdoor in the right-side box to the crafting table. Bring the door into your “ready to use” stock.
