To form a circle with radiating stitches
First mark your fabric with a circle with regular radiating lines either eight or twelve. Next bring the thread to be couched to the surface of your fabric at the centre of the circle. Coil the thread in a spiral and couch down with your finer thread at regular intervals following your guides to form a spoked pattern. Always bring the needle up on the outer edge and angle all stitches towards the centre. Once you reach the end of the spiral required take your laid thread to the wrong side of the fabric to finish. You could couch a series of different size circles in wool threads on natural linen to create a funky cushion!
