Module 1 Chapter 1 Line drawings Turkish tiles

My next sketchbook page consists of a few sketches of Turkish tiles, the stars are very geometrical and it took me ages to do just these few (maths is not my strong point), but I really enjoyed trying to work out how to create the different star shapes. I need to get myself a compass to make them more accurate. While browsing the internet for Turkish tiles I came across this great blog which shows lots of geometric star shapes Y-Knot.
