I have an unused Franklin Planner that I keep for all my supplies. I actually stamp all my stamps into it, categorized like "people", "animals", "flourishes", etc. I have a section for punches where I actually glue a sample of each punch. Other sections I have include Artistic Supplies, such as lists and samples of Stickles, markers, paints, etc. I have a section of favorite websites where I order various things, what tools I have (and order numbers for refills, parts, etc.) I keep the book in my car so I have it for shopping, and only take it in the house to add more items.
