In Minecraft, you’ll need some Arrows if you want to use your Bow effectively.
To make Arrows, you’ll need a Crafting Table, a Stick, a Feather which can be gathered from Chickens, and Flint which is gathered from mining Gravel. Gravel can be found fairly easily by mining near the surface. You’ll know it’s gravel because it’s a dark grey speckled block, and one of the few blocks effected by gravity, so it will fall to the ground if the stationary block beneath it is destroyed the same way Sand does.
Arrange your pieces in the Crafting Table as the picture shows below with the Flint at the top, the Stick in the middle, and the Feather at the bottom. Each combination yields four arrows.
