White canvas, boldly colored fabrics in solids, stripes, and jaunty prints, rattan and cane seating, whitewashed or colorfully painted English case furniture, canopied beds, straw matting-these are some of the signature ingredients of an Amanda Lindroth interior. Since she founded her Nassau-based firm in 2010, she has become the go-to designer of island dwellers from Lyford Cay to Antigua, Abaco to Belize, Harbour Island to Palm Beach, and as far north as Great Cranberry Island, Maine.
