Help Defining Leather types
I am looking to make a project with some leather I have laying around, and just leather products and general, but I can't seem to get straight answers on the Internet. From what ive found, the types of leather are determined by how much grain they have, eg. Full Grain, Top Grain, Split, bonded, suede, etc. What I'm more concerned about are the types of finish. Since i would like to get all natural stuff if I can, i want to find full or top grain analine dyed leather without aggressive surface finish, but I cant find info on what the differences between PU coated leather, pigmented leather, and other surface finishes are. Any help is appreciated
Edit: Thanks for all of the feedback it is very helpful. One more question. I believe the leather I have is oiled pull up or crazy horse, since it has a noticeable color change when stretched. I can't tell if it is top grain or full grain though. What is the difference? Thanks again
