The poster should feature elegant hand-sketched jewelry designs, such as necklaces, bracelets, and rings, showcasing intricate and contemporary styles. Incorporate elements of AI and technology, such as digital design tools and futuristic icons, blending seamlessly with the artistic jewelry sketches. The text on the poster should be clear and inviting, highlighting the workshop's benefits for shop owners. Use a color scheme that is sophisticated and eye-catching, with tones of navy blue, silver, and white. Include space for workshop details such as date, time, and location, ensuring the overall design is professional and visually appealing."
