My system is similar to Mamagus. I use a Rolodex system with their clear sleeves for the cards. I tuck a swatch of each fabric in the back of the sleeve and print out a card with info on the front such as fabric line, manufacturer, where I got it, when I got it, price, how much I have, etc. I keep all the info on my 'puter in a database (similar to that second site thimblebug posted) and print out selected fields for the card. It's easy to update, simple to take any cards to find "go withs", and suits my "office geek" personality. :lol: I don't like binders...had one bite me in the third grade and have not trusted them ever since!! :roll:
