Then I remembered one of my favorite craft books: Martha Stewart's Encyclopedia of Crafts. When you open its cover, the end sheets are printed in a pretty green marbleized pattern.
Then you get to page 168, where the chapter on Marbleizing starts. Lovin' it! (^–^)

...and that's when I started to notice this beautiful art form. I am seriously gonna try my hand at marbleizing paper in the near future.
