Creating Arrows with Artisan: Carpentry and Craftsmanship (p. 271) #

If you use Artisan: Carpentry, you can create makeshift arrows, even when out in the wild. When you attempt this, the check is your technique focus + the bonus from Artisan: Carpentry + 2d6. You create a number of hours (sic) equal to one-third of the final check score per hour. However, because you made these arrows with whatever materials you could find, you take a −1 penalty to hit checks when using them.

You can create arrows in the same way if you use Craftsmanship (p. 273) in place of Artisan: Carpentry. If you do, you will take a −4 penalty on the craftsmanship check.
