I am a color person so I love the bright neon colors for keeping organized during any type of project because I can color-code my notes on the cards with folders sticky notes or any other colorful item I am using for my project. These cards are great if you are using a file box for long-term use of the cards because you don't need divider cards. Just use a different color for each section. It makes it much easier to remove and file back after use. One suggestion is in a recipe box instead of using traditional recipe cards. I make great use of these cards when doing any major shopping. I can use a different color for each person room in our home event etc.
