Usually we can find swirl for classic art design. For feminine, elegant, or even grunge design. Im using inkscape for every design and so glad I found this spiro swirl tutorial using inkscape. Here is a comprehensive video tutorial, (created by syllie) that demonstrates how to use the awesome new spiro swirls feature in Inkscape 0.47, which was released in November 2009. One of the new additions to Inkscape is the possibility to use Spiro curves (Cornu spirals).
