If it comes from an animal hide, it is a leather. If it is not leather, it is a fabric or other textile. End of story. There is no such thing as a vegan leather unless you count the fact that cows themselves are vegan, but there are a lot of other leathers than cow leather.
I have been vegan. I am married to one (most of the time, sometimes she eats eggs/dairy). Not all vegans are militant. My wife realizes that leather is mostly a by product of the meat industry and most leathers aren't made specifically for the leather. Not every animal lover/protectionist/ethicist/vegan is like this. Some are rigid and some are far more relaxed.
I read the article from the OP. Its similar to an advertiser IMO when someone drops in, makes a single post with a link in it and *poof* disappears.
Liquid leather/nylon leather...Those are super not leather. It's like dehydrated water. It doesn't exist.
@migdelysleather25, this is a "came off an animal" leather forum. Regardless of one's desire to carry or use non-animal products, that what this forum is. It's almost like trying to argue religion here. We WANT to work with leather and I think I can say on behalf of everyone on here that we aren't looking for alternatives to leather and we're pretty good at finding the textiles we need to compliment our products. If you want to learn more about "came off an animal" leather, welcome. If not, please don't try to troll. We all know there are non-leather options out there.
