I keep what most would call a storyboard in the binder that has samples of fabric, paint colors (with name and vendor), wallpaper samples, flooring, etc. I also keep in a small pouch in my bag paint chips, wallpaper and/or fabric samples so if I am out shopping and I see something for my home I can match it up right away with the small samples I have with me.
In this binder I also keep ideas that I have found on the Internet, blogs, magazines, and brochures. It works as my dreamboard and the place I start formulating ideas for the rooms that I want to re-do or the few that I have yet to tackle.
I have placed an image below of the cover I created for my binders in Publisher, however, the darling black and white checked border did not show up and that is a shame. It really sets it off! I have binders for everything...household, home inventory/warranties, kitchen notebook, and my great ideas binder.
