Vintage Radio Microphone (Shure 55 style). Grill Texture: The iconic front grill of the mic is the main focus. It is built using horizontal bars of Satin Stitch in silver-grey. Behind the bars, the dark gaps are deep black fabric (negative space). Body: The metal casing is sketched with vertical Running Stitch hatching to show the curve. Stand: The base is a heavy, solid Tatami Fill in dark grey for stability. Accents: "Sound waves" coming from the mic are represented by concentric ZigZag arcs in gold thread. Style: Technical sketch, metallic sheen effect using satin bars.
