The wonderful TABS are from POST-IT and I bought them at Office Depot/Office Max. They are repositionable and you can write on them! Across the top of my catalog I wrote the name of the suites ~ 'Playful Pets', 'Peony Garden','Whale of a Time', etc. Down the side of my catalog I wrote supply categories ~ 'color', 'DSP', 'Tools', 'Ribbon', etc.
searching time ~ you will be pleasantly surprised!
