Watercolour. Tubes are best. Use a lot of paint and less water to get rich colour. In this painting I used a light yellow and ultramarine blue to get my green. the rest are reds of various shades, oranges and some yellow ochre put on in layers mostly. Oh and Indian yellow – can’t do without Indian yellow.
Arches 140 lb or heavier, cold pressed. You need robust paper if you want to get those rich colours to fix. Why Arches? No particular reason, it works well for me so no reason to change.
Allsorts including oil and acrylic brushes. My favourite is an inch flat but a thick one. The hardware store is a good supplier of those. My advice – find the brushes that suit you from ANY source
Yes, I use anything to get what I want and i am always looking for new ways. Wall scrapers, wire wool, wall filler, are all in my paint box. it is so much fun trying out new stuff.
