TESSERA is a big bold sans serif that looks like broken-plate mosaic. Separate Tile, Grout, and Deep Grout fonts make realistic mosaic effects easy, and there’s a companion Fill font that can be layered behind the Grout fonts in a contrasting color or a colorful photo. You can type ^^^ in any of the fonts to make a continuous matching pattern.
If you need a matching font without the mosaic effect, please check out my Wood Shed font.
If you want a more formal mosaic style—serif, square tiles, please check out my Subway Mosaic font.
