Off to the opshop to buy one off white full slip, I chose Dylon's Olive Green If you click on the link you will see how Olive Green looks on Cotton and Silk.
This is how the full slip dyed. A much lighter shade. Oh and by the way I had left this in the dyebath overnight. So longer does not means a deeper colour, at least on synthetics.
