Whenever artwork is posted on forums, on reddit, facebook etc, someone inevitably asks what was used to create it. So here is the equipment and materials I use most often. All links are Amazon affiliate links.
Cheap Brushes It’s good to have a lot of brushes so that you’re not cleaning brushes all the time, and due to the thickness of the paint and the roughness of the canvas, brushes for oil paints wear down a lot quicker than with watercolours. These Royal Langnickel ones are great value but any big bundle of brushes is good.
Windsor & Newton Watercolour Half Pan – Half pan refers to the size of the block of watercolour paint, and is the most common size to buy watercolours in.
Cheap Brushes – It’s useful to have cheap brushes for watercolour if you want to use masking fluid, as masking fluid is rubbery and usually ruins brushes.
Watercolour Paper – I prefer the watercolour block that I’ve linked over pads of watercolour paper. The block is gummed on all sides which means you don’t need to stick the paper to a board, and the paper doesn’t warp so much.
