Well, it seems to me, taking a wild stab in the dark (pun not intended), that nigger-skin is tough like rawhide, and would probably be better for making items like saddles, wallets, belts, and other thick objects where durability is more imporant than flexibility.
Jewflesh, on the other hand, appears to be more buttery, more marbled with fat, and softer in general. Given this, optimal craftwork would incluide chamois-style items, detailing, perhaps thin buckskin jackets and – of course – the famous lampshades.
On the other hand, speaking in genralities, niggers tend to be fatter and flabbier, with them big ole butts and niggahtidddies, while Jews are thinner, stringer, and more sinewy. My guess is that butchering a nig carcass would give you a lot more raw material to work with, in most cases.
What does /edgy/ think?
