Here’s a really cool and useful tutorial map for anyone who is interested to learn how to design banners. This particular tutorial will teach you all you need to know in order to add any of the alphabetical letters to a banner (A-Z). To do that you only need to do some crafting but it can be difficult to know exactly which recipes to use, but that’s why this map was created.
Find the letter which you want to craft and then use the crafting recipes displayed on the wall.
Good luck crafting!
