Dave, you can use your favourit office program with the font "mychain", which Steve included in the program:
- only small letters work, no capital letters
- a dot (".") opens the chain
- a slash ("/") closes it.
- a coma (",") adds a heart symbol
- a semicolon (";") adds a star symbol
Then you can save it as a PDF.
Also check out the font "Scrollsaw".
regards
Torsten
