You Will Need
Use the Molotow Masking Fluid Marker and trace over your entire drawing. Let the masking fluid dry completely, this won't take long at all.
Paint a few washes of watercolour over your Molotow Masking Fluid drawing on your watercolour paper.
TIP: ( make sure you have enough water and pigment in your paint brush to do a smooth clean wash in one go).
Sprinkle a little sea salt on the watercolour paper where you want and it will soak up a bit of the colour leaving less colour behind.
