Playing Rune Factory - where can I get some STRONG STRING?

Question

I've upgraded all my other stuff, but I haven't been able to upgrade this stupid sleeping bag because I can't find any Strong String - is there a particular monster you kill? I got ONE piece of it early in the game and I hadn't gotten any bird wings yet, so I stupidly used it on something else. Any help would be appreciated, thanks!

Answer 1

I THINK you can get it from the flowers in the fourth dungeon.

Try http://ww.fogu.com/hm/ it will have the listing.
