Flatline is an elegant, modern sans serif font family. Meticulously drawn with high contrast between thick and thin strokes with the goal of making even the simplest sans serif letters look sensual, elegant, and warm. It’s perfect for headlines, editorial uses, and advertising projects. Makes beautiful luxe logos and wedding invitations, too. Flatline includes sixteen styles (eight weights each in both roman and italic), each of which includes nearly 500 glyphs. OpenType features include standard and discretionary ligatures, a small number of character variants, three figure sets, four ampersand styles, and multilingual support (including multiple currency symbols).
