I continue doing this, working the white paint and watching the crackled effect take place. As you experiment with the amount of paint you apply, followed by the dabbing up and down brush technique, you will get varying results in each spot. I also recommend leaving small parts of the under colors and the stencils exposed. How much or how little you leave exposed will change up your final look. It is up to you what you prefer.
If you feel your top color is too thinned out, you can fill in with more paint on a subsequent coat, but be careful not to completely cover your crackled look.
