Lorenz Bäumer is convinced that having a special area for sketching in his Paris boutique and hanging original drawings of jewelry designs on its walls has helped distinguish his business from its competitors. “It’s like coming to an artist’s studio and being there with the artist, instead of being at some giant conglomerate jewelry thing that is on the stock market and has 400 stores,” the designer, 57, said. For centuries sketches have been part of the creative process, helping designers to sort through ideas and providing guidance for the artisans who fabricate the pieces. But Mr. Bäumer’s decision to highlight drawing is just one example of the many ways that designers have been putting their sketches to work, using them in everything from social media to sales materials to emphasize the artistry and craftsmanship of their endeavors.
