Use the diagram as a guide when drawing in your cording channels; these are 0.5cm wide and cover the top half of the corset. The number of cording channels will depend on the size of your corset. At the centre back there are two bone channels of 1cm wide and a central eyelet channel that is 1.3cm wide on both sides for lacing up the corset. The front busk channel is 4cm wide; this can be replaced with a smaller busk if required.
