Gouache Painted Postcards
- Remove paper from watercolor block using palette knife, blade, or butter knife.
- Measure paper to 5" x 7" using a ruler and a pencil. Trim to size with an X-Acto knife.
- Tape paper down to work surface to create a ¼" border on all sides.
- Sketch design on to paper using pencil and eraser.
- Apply acrylic gouache colors to your palette and use a dropper to add a small amount of water to each color. Mix until paints are workable and “gliding” on the paper without sticking.
- Color block the beach, water, and sky using a ½" wash brush. Use beige for the beach sand, Light Aqua for the sky, and Cerulean blue for the water. Allow to dry.
- Mix yellow with blue and white to make a sea foam green color for the water. Refine and add in details using a size 6 round brush.
- Add highlights in the water using varying shades of blue, combining the colors to create unique mixtures. Allow to dry between layers of detail.
- Paint the clouds and sail boat. Use light washes of white at first, then build up more layers of white to create texture. Mix a small amount of grey using black and white for shading on the sailboat. Refine your painting with details as needed and allow to dry completely.
- On the back of the paper, use a ruler to make dotted edge lines, space for a stamp, and an address block using a felt tip pen.
- Spray 2–3 even coats of archival gloss spray varnish on both sides.
