Drawing is fun. You can draw whatever you want. You can use paint, pencil, pen, markers, whiteboard markers, permanent marker and more. You can mix colours, but primary colours would probably make brown. You can draw on paper, an easel, a whiteboard, or there are drawing apps. another way of drawing is sketching, or tracing.
You can draw things in books, or colour in things in a book. Things that are easy to draw are flowers, cats, dogs, stick people, apples, and more. you can also draw things that aren't real, or abstract. Nothing is impossible to draw.
You can imagine what you draw and then draw it, but it might not be the same as you imagine it. you can also find something online and try draw it.
Sometimes you can make a lot of money for drawing. Hard drawing can be realistic, cartoon, and more.
