I use the flags in cookbooks to flag recipies I want to find in a hury and I also write on the flag the name of the recipe. The flags are also useful to tag reference books pages.
I use the tabs to mark my scrapbook pages where I still need to add journaling, stickers, letters or pictures. Then I can go back to those pages and remember what I have to do to finish that page. If I need to make letters I put a tab on a piece of paper with the letters I need to make on my Cricut. I have also used it to tag peoples with their names until I can add them with my paper and markers.
Yes, Smart Phones carry almost all the information that we need. But, more and more I discover that it is valuable to have an old-fashioned day planner with me, which helps me stay organized and focussed. Nothing is better than a day planner that you can individualize by using post-it products such as the colored flags. Flag the current week/day. Flag the urgent to do list; flag various assignment sheets for various folks - heck - give them all their individual color. Label them with a permanent marker should you run out of colors... Whenever you have a brilliant thought or idea - document it using the appropriate flagged index. Best of all: your day planner becomes your friend, it does not run out of power or looses bars...Post-It - That's it.
The post it flags are excellant for marking my books and all the reading material, I have on a daily basis. I past them over the first time because I thought they were a little costly, so I bought the cheaper version and needless to say I ended up back and buying the post its. They are durable and hold with the wear and tear of the books. The flags stayed on the pages I marked the whole semester and came off with no damage to the books. This is quaility and worth every cent.
I am a professional organizer and the flags come in handy when I am working on different areas of a person's home or office.
I use them to color code suggestions that I may want to make based on the area we are organizing.
I also use them for blocking off days or periods of time on a specific day.
When I worked in an office, I used the flags as color coding for each of the managers I had. They got use to seeing their color and knew that the stack of papers were for them to review and sign.
