The modular type system FF Stoned is made up of 15 fonts: the basis font FF Stoned Normal, an overlay font FF Stoned Scratches, and 13 ornamental fonts divided as follows: FF Stoned Ornaments One and Two (individual characters), FF Stoned Rule One through Four (for horizontal ornamental lines), FF Stoned Border One and Two (for borders and vertical lines), FF Stoned Mosaic One through Five (for large areas of pattern and tiling effects).
FF Stoned is a family to construct things with. When using several fonts together it is advisable to use the same line spacing and kerning (for the borders and mosaics it is a virtual necessity). The characters in the ornamental fonts are in the positions of the upper- and lowercase letters, and in FF Stoned Rule One also at numbers 1 to 6. Not all of the letters are used; the unused ones are left blank. The Rules (horizontal lines) are made up of a repeating pattern of three characters such as abc. Alternatively, characters of different designs can be combined to form a line.
Borders are built from a basic pattern of eight characters and look schematically like this: abc d e fgh and so on. FF Stoned Border Two also includes three vertical lines that can be constructed from the uppercase characters A through I. As with the horizontal lines, these are built from three repeating characters but can also be mixed and matched. Mosaics are made up of nine characters that when represented with letters would look like this: abc def ghi and so on.
In FF Mosaic Five the patterns are made up of six rather than nine characters and would appear so: abc def and so on. As with the borders, it is possible to combine different Mosaic characters to make your own patterns.
