I absolutely love marbling on old book and dictionary pages (and maps and handwritten letters and ledgers too!). Sometimes I use them to pick up "ghost prints," or the leftover paint in the bath from the original print. But sometimes I set out with colors and patterns that match the specific personality of the page I am marbling on. For me, the point isn't to cover up the beauty of the printed page...it's to complement it...which means I have to be strategic in my colors, design, and intensity.
