The secret to this doodled lampshade? A bleach pen! Put your drawing abilities on display by customizing a boring cotton lampshade with doodled designs. Using a Clorox bleach pen, we scribbled a whimsical design of flowers, leaves, swirls, and figure-8s on a fuchsia fabric lampshade. Work in small sections around the lampshade to avoid smears and smudges. When the designs turn white, rinse away the excess bleach in the sink. Allow the shade to dry before use.
