This is the last tangle pattern I’ve based on Islamic art pieces in the British Museum and the Victoria & Albert Museum. This originally appeared on a glazed terracotta tile in the Nabu Temple, Borsippa (near Babylon) in around 600-500 BC. It seems that all the doodles we do were being done since way way back when! I found it easier to do the teardrops in the border starting in each corner and looping toward the centre circle, rotating the page for each corner.
