As for paints- I have watched others struggle with student grade in both oil and watercolour. The joy on my students faces when they try out artist grade paint for the first time is amazing! Cheap paints contain fillers and artificial pigments ,and are so much harder to paint with. so do yourself a favour, buy the best quality materials you can afford and see your painting skills take a giant leap. If you would like more information about the materials and equipment that I use please get in touch- email@example.com - I'm always happy to help.
