To craft small game arrows in Red Dead Redemption 2 (RDR2), players need the following materials:

• Flight Feather x1 (obtained by shooting flying birds such as ducks, pheasants, ravens, vultures, or owls and then plucking feathers)
• Regular Arrow x1 (can be purchased at gunsmiths or general stores)
• Regular Shotgun Shell x1 (can be purchased at gunsmiths or general stores)

Crafting requires starting a campfire in the wilderness (not in town or gang hideout), then accessing the crafting menu from the campfire. Under the ammunition section, players will find the option to craft "small game arrows" if they have the required materials. It is important to have the flight feather specifically, as turkey feathers do not count. The recipe may also require viewing the small game arrow pamphlet from the fence to unlock, though some players get it automatically. Small game arrows are especially useful for hunting small animals like squirrels, rats, snakes, toads, chipmunks, bullfrogs, bats, and small birds to obtain perfect pelts for crafting or selling. In summary, to craft small game arrows:

1. Get flight feathers by shooting birds and plucking feathers.
2. Purchase regular arrows and shotgun shells.
3. Set up a campfire in the wilderness and open the crafting menu.
4. Go to the ammo section and craft small game arrows using one flight feather, one arrow, and one shotgun shell per arrow crafted.

This process ensures players can efficiently hunt and gather perfect pelts from small game animals in the game.
