There are lots of things I do to keep myself organized. I have a Mead 9.5" x 6" notebook that I list every card I make and the recipe along with a unique number (I'm now at 2417 - two thousand, four hundred and seventeen cards I've made). When I take a picture of this card, I name it 2417. When I add this photo to my blog, the name changes to 2417-blog. At a glance of this directory I know which cards have made an appearance on my blog and which haven't. I can also do a search of all cards that have made it to my blog and, of course, I can see the picture of each card. I am religious about my notebook, it stays on my desk all the time and each supply that makes it to a finished card goes into the notebook, along with its number. I use it as a reference almost everyday. When I package the card, I use a circle sticker on the back of the cellophane for the price and also include the number of the card. I write that number down when I sell a card and update my notebook with a small stamp next to the recipe for that card. Some cards I've recreated many times because they are big sellers and each time I sell another one, I re-stamp the notebook. It's easy to tell which cards are my best sellers. Sometimes I take multiple photos of one card, perhaps to show a detail. In that case, those picture's names have a letter behind them, starting with a, 2417a.
