Banners can be designed more precisely by using a loom. You will also need to have other items to create a red-and-white striped flag.
Before you start making your flag, there are some things that you need. A White or Red Banner must first be created. From bones taken from Skeletons, bonemeal can also be made and used to make White Dye. White Dye can also made using the Lily of the Valley Flower. This flower has a 1:1 ratio. One bone will make three bones to make three White Dyes.
Red and blue dye will also be required. Red Dye is made from Poppies, Red Tulips and Beetroots. Blue Dye can also be obtained by Corn Flowers and Lapis Lazuli.
To put everything together, you will need the Banner and Loom. Two wooden planks are all that’s required for the Loom recipe.

For the base, the banner should be either white or red. No matter what color you choose, the banner will have the same stripes at both the top and bottom. The many patterns you have to choose from will be revealed by placing the banner in the Loom with the opposite dye. Use the Paly Pattern to create stripes. This will include the Dye prefix.
The blue corner of your flag can be made using the Chief Dexter Canton pattern from the Loom’s menu. The flag is ready to hang or be placed on a Shield once the design has been completed. The banner can be easily duplicated by players making blank banners and crafting them using the flag. The American Flag will be placed in the middle of the crafting grid. You can also place a blank banner under it to replicate the design.
