After being charged with decorating the 12,000-square-foot interior of historic Evermay mansion in less than seven months, Jodi Macklin and assistant Lauren Sparber found these Washington area purveyors.

Salvations Architectural Furnishings : Iron fire screens for 12 fireplaces were designed by Silver Spring designer Barry Remley, owner of Salvations, and hand-forged by local blacksmiths. Remley’s firm also made a coffee table with an iron base and a limestone top for a meeting room, and several other small tables. Find pieces at Urban Country in Bethesda and area Kellogg Collection stores.

Timothy Paul Bedding + Home : All those bedrooms needed distinctive sheets, duvet covers, pillows, coverlets and shams that would blend in with the rugs, fabrics and furniture. Since each bedroom had a different signature color, Macklin and Sparber spent time mixing pieces at this small Logan Circle shop with owner Mia Worrell. The store specializes in a unique selection of textiles in many textures and fibers. 1529A 14th St. NW, 202-234-2020.

Simplesong Design : The designer wanted to create a clean, simple and stylish “Kindly Do Not Disturb” sign that would do justice to the newly restored door hardware. She reached out to artist Suann Song, owner of a letterpress business. Song created the custom designs — letterpress printed on extra heavy white cotton stock— and attached antique brass chains to hang on the doorknobs. 1511 King St., Alexandria, 703-548-0018.

Hemphill Fine Arts : Macklin and Kuno worked closely with George Hemphill to select meaningful art for some of the major rooms of the house to complement the interior design and Evermay’s history. The works chosen include “Virginia Hills,” painted by Washington artist Jacob Kainen in 1946. It hangs in the second-floor meeting room. 1515 14th St. NW, 202-234-5601.

Addison/Ripley Fine Art : Sachiko Kuno fell in love with the work of landscape colorist Wolf Kahn and the floral abstraction of Edith Kuhnle on a visit to this Georgetown gallery. Christopher Addison and Romy Silverstein helped locate paintings by these artists for the living room and foyer, as well as the cherry blossom photographs by Frank Hallam Day in the “Cherry” bedroom. 1670 Wisconsin Ave. NW, 202-338-5180.
