greek key shape: T | turns: 4 | meander: Yes |lines: Yes | This pattern is drawn form scratch using guides from http://gwydir.demon.co.uk/jo/greekkey As I read here, redrawing of the generator is permitted. This are universal ancient shapes used form thousand of years. So I think that will not be a problem to be released to public domain. http://gwydir.demon.co.uk/jo/greekkey/save.htm "Of course, you can also copy the design by hand. Or you could copy the generator of the pattern that you want, then enlarge it, colour it and duplicate it as you wish"
