Storage Room Dozens of examples of her brightly colored graphic prints are on display in some form — a rack of silky dresses, linen jumpsuits, and color-blocked jackets from her spring collection greet guests as soon as they walk in; a stack of dog beds, usually occupied by her Boston terrier, Snips, is in one corner, across from a pile of patterned and embroidered throw pillows; shelves are stacked with graphic bath and beach towels, fruit-printed bed linens and cozy blankets; poster boards of some of her most loved prints are both hung and leaning against any available wall space.
