Book your place — £49 → An introduction to water-soluble oils — a full day with guest tutor Les Trewin. Oil paint without the solvents. Water-soluble oils behave like conventional oils and finish like them too, but the brushes wash out in water — which makes them a genuinely practical way into oil painting. You will make your own small still-life study over the day. Les begins with the medium itself: how it differs from conventional oils, what it does well, and what it asks of you. Then the underpainting — an imprimatura in burnt sienna — building the tonal values of the still life and learning how contrast creates form and depth. After lunch, colour: mixing and matching accurately from a limited palette, working thin to thick and dark to light, and building the layers that give a painting its depth. You will finish with advice on varnishing. By the end you should have the skill and the confidence to pick up water-soluble oils on your own. No experience needed. Boards come ready gessoed with a still-life drawing prepared for you, and you take home a palette with enough paint to finish your piece if you would like to. Friday, 10am–4pm , with half an hour for lunch, at the Cornish Craft Barn. Book your place →
