Bello connects the black sand from Lake Michigan to the beaches in Davao where she and her siblings spent nearly every weekend of their childhood. Discovering that the Rio Grande Rift as a north-trending continental rift zone, “it made me think of the North Star (Polaris) that has been used for navigation since antiquity.” The cartouche bears a journal entry about her trip from Taos to the coast of Oregon where she spent a month of her residency looking across the Pacific Ocean “to visualize the archipelago where I was born around 2,000 miles from the shore.” "Line" is subtitled with the astronomical coordinates for the North Star.

"Air, Line, Color" is inspired by jewelry with the same title made by multidisciplinary artist, Stephanie Simek, whose necklace of semiprecious stones was akin to a talisman Bello brings with her to all her artist residencies throughout the U.S.
