I use gesso or linen boards, unless I’m painting larger than around 70 x 50cm. Then its good quality stretched linen canvas,
My paint brushes are usually Ivory flats and filberts from Rosemary Brushes. If you contact them here, you can buy my set – which consists of: Ivory Filberts size 2 and 4, Ivory short flat size 6, Ultimate Bristle filbert size 6 and an Ivory rigger size 0. The Ivory brushes are firm and perfect both for moving the oils and ‘placing’ the paint softly. The Ultimate Bristle is great for getting a bit mor paint on the canvas when you need some thick highlights – and the rigger is good for some splashy noise and any refined edges you might want at the end of the painting.
I use low odour solvent – both for cleaning brushes and thinning paints. I don’t really use a medium. I like Zest It, Robersons Studio safe solvent or Jackson’s own, here, which is great for air travel due its high flashpoint rating. I have a brush washer like this one.
