I made a tutorial with lots of pictures on how to use Masking Fluid for watercolour a while back, and I just posted it to my website's blog for easy reference.
Take a look: http://liquidflare.net/tutorial/2018/watercolour-basics-masking-fluid/
I'm hoping to do more beginner watercolour tutorials in the future! Let me know if there's a topic you'd be interested in me tackling. :)
@Rheall hi! yay tutorials! The thing I struggle most with is layering, and having the patience to let things dry between layers. So maybe something like trees with depth or mountain landscapes or something like that?
@bouncinglime Ooo, that's a great idea! Thank you! I'll see what I can come up with. :)
