Lunasea, For one thing, if you don't know that you need vegetable tanned leather to tool a design- you need to start from the beginning and learn the basics before doing any project of this magnitude. Yes, I believe you're too ambitious. Start with something simple and learn what you need to know before moving ahead. Learn from videos on the internet or go to the Tandy leather factory site. It has tons of videos and info. Good Luck!
