A minimalist fine line logo for a flower studio, on smooth warm cream paper (#F6F1E7) with a faint paper tooth and flat, soft, even daylight. Wide empty margins: the lockup fills only about 50% of the canvas width, centred, and the rest is clean paper. Left of the lockup: a single fern frond standing upright and slightly curved, about 55% of the canvas height. It is drawn in one thin, even charcoal ink line (#2B2B2B), like a single-needle tattoo or a 0.1 mm technical pen. One slender stem curves gently upward and tapers to a curled fiddlehead tip at the top. Paired, narrow, pointed leaflets are drawn as open outlines along both sides of the stem. They are largest at the base and shrink steadily toward the tip. The line is never filled, shaded, doubled or sketchy, and every stroke keeps the same hairline width with crisp ends. Behind the lower third of the frond sits one soft flat blush-sage shape (#C9D4C0), a loose organic oval that the line drawing overlaps. Right of the frond, vertically centred on the frond's middle and set close to it: the name "Wild Fern" in a delicate joined cursive, written with the same single hairline stroke as the frond. The script is lowercase-led with a small compact x-height, a gentle forward lean, tall slender loops on the ascenders and open-loop capitals W and F at ascender height. There are no swashes, tails or underlines. Strokes are the same hairline width from start to finish, with clean stroke ends. The name is about 28% of the canvas width and reads as quiet and dainty, in the same charcoal ink. Frond and name share one line weight, so they read as one drawing. No other text, no border, no extra motifs, no gradients, no shadows.
