Celia started her demonstration by setting up a still life containing flowers.
She then loosely sketched the composition on to stretched watercolour paper (Saunders Waterford) using a water soluble pencil. She then proceeded to add colour loosely using mostly wet techniques. For the main flowers, she first painted the area with plain water before adding colour. Sometimes she would drop in extra colour while the paint was still damp. Sometimes she would lift colour out using a damp brush.
She used a single brush for the whole demonstration. This was a large oval wash brush of squirrel/synthetic mix, which held a lot of paint but also had a good point. It proved to be extremely versatile. Celia showed how it could be used to provide a graduated effect by loading more paint to the tip, and also blending by loading two colours to the brush and allowing mixing to occur on the paper.
Some photos of her demonstration are shown below.
As the demonstration was nearing the end, Celia was asked how she would tackle the background. One method she sometimes uses, particularly where light objects need to be brought forward, is to add some strong wet colour adjacent to the light area, spraying the background area with clean water using an atomiser, then tilting the board to let the colour run. This can be seen below the yellow flowers just above the coffee pot.
