Kolam Inspired Simple Knot Tutorial

The inspiration for this knot came from several KOLAM designs I've seen on the web.
I have use it as a center in some of my latest mandalas.

For this tutorial I've used

 Stillman and Birn Zeta Series Wirebound Sketchbook (6x8 in 15.2x20.3 cm)

Staedtler Triplus Fineliner 334

Step 1 Start drawing a cross.	Step 2 Add perpendicular lines to each arm of the cross.
Step 3. Draw three lines on each space following the direction os the external line. Its easier to add one in the middle and then one on each side	Fill the four spaces. It should look like this.
Step 4. Start drawing the curved lines' start with the one closest to the middle.	Continue drawing the four curved lines, one for each straight line. The last one should start at the external line you drew in step 2.
Continue drawing the curved lines on each side of the square, following the same order.
	Here's you finished simple knot.
