Thank you and yes I use watercolours. I use a mishmash of watercolours that I've sort of accidentally accumulated over the years... I have a little 14-pan Winsor&Newton watercolour set, a kids' watercolour set I got from a poundshop and some tube colours I picked up just because I liked the look of them. Anything goes really. And to learn to use them is just mostly practice... I haven't had actual proper lessons about them either except for random tidbits in high school art class. It's all just trial and error and sometimes you come across tutorials that teach you new tricks to try so get painting!
