Here are a selection of sketches made in Crete. The sketchbook is Jackson’s Art Supplies’ own brand, 160gsm watercolour paper, cotton blend, about 8″ x 9″.
I used some of the local earth as pigment, to make a watercolour, using Schmincke watercolour binder.
I ground the earth using a stone, breaking it up to make a powder like talcum powder. It still had bits in, but I managed to separate it by shaking, and scooped most of the bits off the top with a teaspoon. Then add an equal quantity, by volume, of the binder, and scoop into a suitable receptacle. It can be used immediately: it has the consistency of paint from a tube. Or. leave it to dry, then it’s like a watercolour pan. The “suitable receptacle” here is an empty butter portion container.
The watercolour works amazing well. It is a rich red-brown colour. Ideal for painting the surrounding scenery.
You can see it, for example, in this picture:

Your work is excellent. Very pleasing to eyes too.
