Steps for Achieving a Flat Watercolor Wash:

Here's how you can achieve a flat wash:

Prepare Your Materials:
- Use a suitable watercolor paper.
- Have your chosen watercolor paints and water ready.
- Use a brush that can hold enough water and paint.
Load Your Brush: Dip your brush into water, then load it with diluted watercolor paint. The mixture should be watery, similar to the consistency of milk, so that the paint flows evenly and does not dry unevenly.
Start Painting:
- Begin at the top of the area you want to cover.
- Paint a horizontal stroke from left to right (or right to left if you are left-handed).
- According to the video reference, you will want to "paint the paint on the paper from left to right" and then reload your brush.
Continue with Overlapping Strokes:
- Reload your brush with paint and apply the next stroke, slightly overlapping the previous stroke, this is important to prevent hard edges and ensure a flat, smooth application.
- The reference explains that "I'll lay in another stroke. And then I'll just go back and forth across the paper like that." This "back and forth" motion is how you cover the area evenly.
Keep the Wash Wet: Maintain a wet edge as you move down the paper. This is key to prevent noticeable streaks or hard lines where strokes overlap. Work quickly and maintain a consistent flow.
Avoid Disturbing the Wash: Once the wash is laid down, try not to go back into it with your brush too much, as this can create uneven patches. Allow it to dry on its own for the best results.

Use Enough Water: A watery mixture is essential for a flat wash. Too much pigment and not enough water will cause the wash to dry unevenly.
Work Quickly: Watercolor paint dries fast. Working in a timely fashion will help achieve an even wash.
Practice: The more you practice, the better you will become at achieving the perfect flat wash.

Overworking: Repeated brushstrokes can lift the paint and cause unevenness.
Dry Brush: Make sure your brush is always loaded with enough paint and water.
Uneven Paper: Make sure the paper you're painting on is completely flat, to avoid the paint running into pools.

By following these steps and tips, you can achieve a smooth, even flat wash in your watercolor paintings.
