<ul><li>Method </li></ul><ul><li>Construct two concentric circles, one of which is twice the radius of the other </li></ul...
Step 1:  Draw a vertical line and a horizontal line intersecting at point A near the centre of the page
Step 2:  Centre compasses at A and draw a circle with radius 50mm
Step 3:  Keeping the same radius, centre compasses at B and scribe arc B A C
Step 4:  Draw a circle centred at A with radius A C
Step 5:  Keeping the same radius, draw two arcs at each point C D E and F to intersect with the circle AC
Step 6:  Draw construction lines through the centre point, dividing the circle into twelve parts
Step 7:  Draw a moulding with radius 90mm
Step 8:  Draw   a moulding with radius 60mm and mark off six points around it
Step 9:  Draw six circles centred around the inner circle so that they are all touching each other
Step 10:  Draw mouldings with radius 25mm
Step 11:  Terminate all circles at their intersection with the inner circle
Step 12:  Remove the inner circle
Step 13:  Clean up construction lines and darken outlines
