How to Sketch Before Watercolor Painting

Before you paint a watercolor piece, sketch loosely to work out your composition first. Start with a border to frame the piece, then lightly sketch where everything goes, keeping proportions relative to each other. Use a straight edge to capture angles on any man-made structures, whether you're working from a photo or painting outdoors.

Why This Matters

A border isn't just decoration, it helps you frame your watercolor composition before you commit to paint. Once you know your edges, you can decide where everything sits inside them, including nudging a structure off-center so it doesn't land right in the middle of the piece.

Sketching loosely, rather than rendering every detail, keeps you focused on proportion and placement first. The details can come later, once paint is involved.

Try This

Before your next watercolor painting, draw a border first. Then loosely sketch in your major shapes, checking that everything stays proportional to everything else around it. If you're including any man-made structures, hold a straight edge up to your reference (or your actual view, if you're painting outdoors) to capture the angle accurately before transferring it to paper.
