Quantity and Packaging
When it comes to quantity, I always consider how many cards I realistically need. Buying in bulk can save me money, but I also want to ensure I have enough variety to keep my projects engaging. I prefer packages that offer a mix of colors and possibly some blank cards for my more creative endeavors.
Storage Options
Proper storage is essential for maintaining the quality of my index cards. I often look for boxes or organizers that can keep my cards safe and accessible. Having a designated space for my index cards not only keeps them organized but also makes it easy for me to grab what I need in a hurry.
