My tutorial for Mosaic in the round is free: Inca Flower 1
Inca flower is video supported for the fist 19 rounds. It is suitable for a beginner in overlay mosaic crochet. In videos I explain the chart and stitches. I also added a written pattern, so together with the chart and video’s it is a simple to follow pattern

Yarn used: DK, acrylic (Hobbii Tweed Dreams) Dark colour 125 meters, 140 yards Light colour 125 meters, 140 yards
