Step-by-Step: How to Make Watercolor Hearts

1. Tape down your postcard
   Secure the edges of your watercolor postcard with washi tape. This helps create clean borders and keeps the paper from warping too much as you paint.

2. Lightly sketch hearts
   Using an H3 pencil, sketch your heart shapes lightly. Keep the lines simple and playful—no need for perfection here!

3. Soften the sketch
   Erase any harsh lines and lighten your sketch to a faint outline. This will let the watercolor shine without pencil lines showing through.

4. Add a background wash
   With a diluted mix of watercolor, paint a light background wash over the postcard. This will set a soft tone behind your hearts.

5. Blot with tissue
   Gently blot any areas that feel too wet or dark using a tissue. This adds texture and keeps the paint from pooling.

6. Paint the hearts
   Begin filling in the hearts, starting from the center and working outward. Use soft layers of watercolor to build color.

7. Outline with deeper tones
   Once dry, outline each heart using a more concentrated version of the same color to create depth and a soft pop.

8. Layer and blend
   Let each layer dry before adding more paint. This creates beautiful, dreamy gradients and adds dimension to your artwork.

9. Peel the tape
   Once your painting is fully dry, gently peel off the washi tape to reveal crisp, clean edges. Ta-da!
