A cybersigilism thorn band tattoo design in fine black line, wide and low like a collar or armband ornament. Two mirrored thorny vines with curled spurs run outward from a small sparkle star at the centre, on off-white textured paper. Replace the centre star with your own symbol or change the ink colour.

Cyber sigilism tattoo design for both collarbones, drawn as black linework on a plain off-white paper ground. The piece is a wide, shallow horizontal band, perfectly mirrored on one vertical centre line. At the exact centre sits one small four-pointed sparkle star with concave sides and needle-sharp points, about 6% of the canvas width, with a tiny gap of empty paper around it. From the star, two matching ornaments run outward left and right, each about 40% of the canvas width. Each is a long, slender central spine in a gentle S-curve that rises slightly then sweeps down and out along the collarbone. The spine swells slightly in its middle and tapers to a needle point. Along it grow thin curved thorns and hooked barbs alternating on both sides, with some branching into split, double-pointed tips. Two or three long curving spikes sweep out and down at each outer end, tapering to fine points. A few thin secondary veins branch off like circuitry. Keep generous open gaps between all lines, so that no lines touch, cross or merge, and every line stays clear enough to stencil. Every stroke is a single needle-thin line, with razor-crisp edges and no fills, no solid black masses, no thick tribal bands, no shading, no gradients. The linework is flat, even and pure black on a clean light ground with a faint paper tooth. No text, no letters, no numbers, no body, no skin, no mockup, no frame. Keep all elements inside a safe margin of at least 8% on every side.
