Cut your cardstock to a clean rectangle and round the corners if you want a smoother, softer look.
Lightly sketch a simple soundwave shape near the top. It doesn’t need to be perfect as the hand-stitched style is what gives it charm.
Use a needle to poke small holes along the wave line, spacing them evenly so the thread lays smoothly.
Stitch through the holes with red thread, going back and forth to create a continuous, flowing wave. Tie knots securely on the back.
Draw the screen border, song title, and music player icons using a fine-liner. Keep your lines relaxed; the handmade feel is part of the aesthetic.
