Neutral tones add to the calm and soothing atmosphere.
This extra strength allows it to be seen through the top masking coat. For the base coat finish I recommend a Satin Paint, because it is smooth, and the sheen makes it easier to apply the top coat paint. You may use other finishes if you like. Flat sheens will stick and create a more rubbed appearance, whereas semi-gloss finishes will remain very smooth and pick up less topcoat color. Let the basecoat dry at least 24 hours before starting the next step.
