There is also a link at the end of the article that will take you to a list of all the tips from the video if you sign up for a free account on the site.
If you are looking for inspiration on how to organize your scrapbook stuff (or how to make room for all that yummy new stuff from CHA-Summer), there is a great archive of organization basics for scrapbookers at the Scrapbooks Etc. website.
The section is organized by type of supply being stored, and there is also a wiki section for reader organization tips and discussion.
