Anyone who's shopped for floor coverings recently knows they usually come in two types: the wrong color that fits your space perfectly, or the perfect pattern that's only two feet too wide for your room. You can find the third type -- exactly what you want in exactly the size you need -- at Allure Custom Rugs. For more than a dozen years, owner Avner Giladi and his artisans have been transforming individual designs into custom rugs. The carpets, available only through interior designers, take about two months to create and are never of the fourth type: cheap. Most cost between $40 and $90 per square foot, depending on the design. The rest of us can watch the rugs take shape with a tour of the Allure factory; call for an appointment.
