I think it would be really cool if you could take the nesting materials you buy from the general store and 'rip apart' or 'open' them just like a toy bundle! and you would get 1-4 items with a total usage of 4 (my thought is that ripping apart the nest damages the items inside/also prevents opening nests then recrafting over and over)

Now why on earth would you willingly want to do that?

The items would be randomly generated! So it could be a nice way to get large leaves or underbrush or some elusive herbs or feathers!
