Sometimes you just have to let the watercolor paint and paper dry at its own pace. If you rush it, you will ruin it!
Magical things can happen when you allow the paint to dry and leave it alone.
Resist the urge to rush back in and touch things up. Change things around. Fix this, fix that. Especially while the paint and paper is at that stage between wet and dry. That damp stage, no matter what you do, you will ruin it. You'll make it worse.
Leave it alone, let it dry and it will be better than you imagined.
