Guilloches were - in the old days - used to make the falsification of bankknotes more or less difficult. The engraving of these intricate lines was done by a highly specialized mechanical machine, which was operated by an equally highly specialized engraving artist. Once the settings for a specific curve were changed back to zero it was very difficult, if not impossible to set them back to the old design. I have designed a useful set of Guilloches that join to form ribbons that create a kind of op-art 3d effect. Under the keys A-U and a-u you find joining pieces. Under the keys V-Z and v-z I placed start- and endpieces. 0-4 are different lenght straight extensions and 5-9 are not quite so straight extensions. All other keys are cornerpieces that can be used as standalones or put in rows to make for superb decoration. With a little bit of experimentation and maybe colored overlays you can achieve super-phantastic designs. Your elegant type designer Gert Wiescher P.S. I will gradually extended this line of Guilloches, so watch out for new designs all the time!
