Quick Answer
The iHeartArt Watercolor Postcard Pad is perfect for creating mail-ready art. Start with simple washes and let each layer dry before adding details.
Why Postcard Size Works for Watercolor
The 5.8" x 8.3" size is ideal for quick painting sessions. You can finish a small scene in under an hour, which is great for beginners or busy crafters.
Because the pad has 20 sheets, you can experiment with different techniques without worrying about wasting expensive paper. Each sheet is a fresh opportunity to try something new.
Choosing the Right Subjects
Start with simple subjects that don't require fine detail. Landscapes, sunsets, and abstract washes are forgiving and look impressive with minimal effort.
For a personal touch, paint a favorite place, a pet, or a simple floral motif. These make thoughtful mail art that recipients will treasure.
Step-by-Step Painting Process
- Prepare your workspace: Lay down a protective cover, have water and paper towels ready. Tape the postcard to a board to keep it flat while you paint. Checkpoint: Make sure your paper is secure before starting.
- Sketch lightly with pencil: Draw a simple outline of your subject. Keep lines faint so they don't show through the paint. Checkpoint: If the pencil lines are too dark, erase gently before painting.
- Apply the first wash: Wet the area you want to paint, then add color with a large brush. Work quickly to keep the wash even. Checkpoint: Let the wash dry completely before adding more layers to avoid muddy colors.
- Add details and depth: Once the wash is dry, add smaller shapes and darker values. Use a fine brush for details like branches or waves. Checkpoint: Stand back and check the balance of light and dark areas.
- Let it dry and flatten: Allow the painting to dry fully. If the paper curled, press it under a heavy book for a few hours. Checkpoint: The postcard should lie flat before you write on the back.
- Write your message and mail: Use a ballpoint pen or marker on the back. Write a short note, add a stamp, and send it off. Checkpoint: Ensure the ink is dry before stacking postcards.
