I have done ALL of Jyotsna’s courses and they are brilliant. The presentation is really nice and the content has set me off on a kind of obsessive exploration of hunting for colours in nature, making pigments and the excitment of seeing what colours will come (often unexpectedly) from a plant. If you are interested in pigment making then do those courses and then the paint making one as you will then have your own ‘materials’ ready. Go for it!
