A hand made cyanotype blueprint on sturdy 12X18 watercolor paper. Each is unique, and likely to feature small imperfections.The blue will fade if left in the sun. If this happens, it can be darkened by placing it somewhere dark with good air flow to re-oxidize the ink. Alternatively. hydrogen peroxide, available from grocery stores, will instantly oxidize the ink and restore it to its full hue.
