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.
Well in the old days index cards were actually that...index cards. Now unfortunately they have thinned out the card stock to practically a paper stock. So they shouldn't be called "cards" anymore. Index paper is more like it.
I am a novelist I write novels and when I revise these cards help me know which things need work and which do not. they are good for keeping things separate and learning what I did correctly and what i need work on. They tell me where most of my work in revision needs to go and to me that if a perfect use an exact need they fill for me. I would wish they made the red ones in their own pack but that is just me as I do often have to add scenes to my works and the red is the card I use for that. thank you Staples for selling them in these bright colors as pastel are too pale.
