For the quick, yet dramatic makeover in a guest room in a rented Marblehead beach home, interior designer Helen Bergin used removable wallpaper from Think Imprint by artist Ana Cristina of Puerto Rico. “It’s a wave pattern,’’ Bergin said, “but others see pickles and Dalmatians.’’
Bergin chose a custom red-lacquered bamboo frame from Boston Art & Framing in Beacon Hill for the 1953 Picasso lithograph (which was purchased on eBay) to draw the eye upward.
The 1940s piece from Cambridge Antique Market, which has the original brass hardware and was refinished in bright red paint, was the starting point for the room. “I fell in love as soon as I saw it and struck a deal,’’ she said.
The sharp-edged pattern of the bedding, “Bang Bang’’ in Ketchup by Los Angeles-based designer Jill Sorensen, is a nice counterpoint to the freehand style of the wallpaper.
The cockatoo lamp, from Art & Antlers in San Francisco, was an Etsy find that “provides the perfect amount of quirk,’’ Bergin said. The violet lampshade throws the color palette purposefully off kilter.
