We'll be using these two techniques all the time. Glazing/ Layering is arguably the most important aspect of watercoloring and it makes it quite easy for us to get cool textures and effects.
The Wet-to-wet-technique is useful in order to achieve relatively smooth gradients. We will use it less often in this tutorial, because the wet-to-dry-technique (or dry-to-dry) is much better suited for the rough textures we’re aiming for.
One advice: keep a sheet of paper handy in order to experiment with different combinations before applying them to your artwork. It’s very hard to correct mistakes with watercolors if anything goes wrong, so better safe than sorry.
