I know that there is at least one other mod out there that will allow one to forge arrows. However, mine will allow the player to forge ANY arrow in the game from Falmer to Draugr. Each arrow (except Falmer) requires firewood, fletching feathers, and an ingot of some kind (the feathers can be bought from blacksmiths). I also added the Nord Hero arrows (the ones used in Sovngarde) as a bonus. Note: this mod can also be found on the Steam Workshop, where I go by "DEVASTATOR".
You can find the arrows under the "misc" tab on the forge's menu.
