Watercolour over wax resist, 176 x 228 mm, Private collection

Wax resist allows for the use of wax, for example you draw
with one end of a candle.
If you paint over it with water-based paint, it will not
adhere to it as the wax resists the colour.
The light lines in the green and yellow areas were drawn with
wax.
