Every stroke in this family holds one even hairline width, so the letters read as drawn paths with nothing filled in, and the ornamental treatment rides on that same thin line. Relief SingleLine Ornament comes from François Chastanet, Noëlie Dayma and Élisa Garzelli at institut supérieur des arts et du design Toulouse, whose isdaT type program releases its typefaces publicly on GitHub. It sits in the sans serif category, and the family here has two files: the Regular plus a second style. Latin coverage runs past 89 languages.

A single-line skeleton earns its keep when a pen or a cutting head traces the path instead of flooding an area with ink. Pen plotter print editions and CNC-routed workshop signage both suit it, because the nib or the bit follows each stroke once and lifts. The ornamental styling also holds up at headline size on risograph zine covers, where a heavier display face would clog the paper. With Latin support this wide, bilingual gallery wall text can stay in one typeface across both languages.

Pair it with a quiet neutral sans for body copy, something with real stem weight to balance the thin line above it. Relief SingleLine Ornament is free under the Open Font License for personal and commercial use, and the files download directly from this page.
