Whats the best place to get cheap but safe arrows? Or, failing that stuff to make them?

I recommend david dukes at In Your Dreams FX … 03?fref=ts

I second In your Dreams FX, very reasonably priced, Dave Dukes is very helpful and approachable.

Twisted Flax LARP Kit (look on facebook). Excellent arrows, very reasonably priced. Also good bows and other archery supplies, all at fair prices.

Perhaps also Quiverstock? L13 each though… you can probably find cheaper.

(Meanwhile, I think Twisted Flax is no longer in business, alas.)
