With pride I present Curlz, an extended project and my first triangle shaped pattern.

Curlz comes in Overlay Mosaic and Interlocking Filet crochet. Both techniques come in row to row (rtr) from the center out (co) and in triangle shape (shawl).
The overlay mosaic crochet pdf also has a smaller version included for all 3 techniques.
You get a lot of patterns and techniques to try
