Crafted Items based on what is gathered.

I was thinking, why not have crafting more special by crafting items from things gatherd. heres an example, its hard to put in words.

Alligator Hides - Alligator Belts, armor, boots etc.. with skin pattern of the alligator/crocodile
Pine wood - Pine box pine, wood stuff (colored darker brown)
Poison glands from spiders - poison potions
Scorpion hides - Scorpion armor like banded or something
Wolf Cape, boots from wolves
Bear cape, boots from bears
I think it would make crafting a lot more rewarding.
