I have been digging around here and on google, but haven't been found any sources of in-depth information on this. I am looking to order a custom leather jacket, and would like to read about different lining materials, zippers, etc. The maker (Johnson Leathers) told me that some of his customers provide their own lining. If I learn about a material that I really like, then I may do that (this will be a cold weather jacket). Anyway, if one of you gents could point me in the direction of some articles o guides, I'd appreciate it.
