Step 1 Start with a circle in a square, divided into eight equal sections (you can download and print a template here).Islamic geometric pattern by Eric Broug

Step 2 Draw four lines that pass through the intersections indicated with red circles. Consider the lines as two opposing V-shapes. The lines do not end in the corners of the square.

Step 3 Draw another two opposing V-shapes, using the same intersections as in the previous step.Islamic geometric pattern by Eric Broug

Step 4 All the construction lines have now been drawn. Take a different colour pen or pencil and draw the red lines, tracing parts of lines you have drawn in the previous steps.Islamic geometric pattern by Eric Broug

Step 5 Still using a different colour pen or pencil, draw the four-pointed star, as indicated.

Step 6. All the lines have been drawn, your pattern is complete.

Step 7 Your pattern without the construction lines.

Step 8 Now you can tessellate your pattern in a grid of squares to make a bigger composition. If you’re working in a group, tessellate all the patterns together.
