At Tuscan Rose she calls her project Scrapodex. Her project is from a few years back but if you click on Scrapodex in her category list she has a lot of posts about her project.
Collage artist Seth Apter called his project Rolodecks. He didn't have a Rolodex so he used a small box as his holder.
Kristin Peterson at Altered States Studio often uses Rolodex cards to get her creative juices flowing.
My sister has created a few more cards for her project of positive quotes:
One of the things I am enjoying about this project (besides the fact that it includes vintage office supplies) is that it's quick. My cards are 3 x 5. Once I built up a little stash of covered cards it was very easy to fit a little art in after a busy day and complete a full card in a short amount of time.
I'm going to fill the "A" section with a card a day for Advent.
