In the kit were 5 different colors of ink in dropper bottles. The instructions directed me to make a salt water solution upon which to float drops of the ink. The ink behaved strangely - I couldn't tell if that was part of the nature of this ink, or if it had become clumpy over time. It did float, as one might expect, but it didn't swirl like I thought it should. The bold primary colors were not particularly appealing, either.
The kit also included the bases for some projects that the marbled papers could be used. Among them were bookmark blanks. Since the bookmarks were longer ( 8 x 2 inches) than the pieces of paper that I marbled, I decided to cut up the paper and piece it onto the bookmarks.
