Best Place To Get A Sample Book

[Steel City Phantom]

yea, im a noob.

i am trying to learn the different types of leather. the weights, the textures, the finishes, etc to find the best fit for the projects i want to do. is there someplace where i can get a sample book with a good variety of swatches of varying weights, textures, and finishes? im not so much concerned with colors at this point, more weights.
