Painted Pastel Seashell Pumpkin With Stripe Details

Clean, dry, and base coat the pumpkin

Wipe the pumpkin with a damp cloth and let it dry fully. Apply a thin, even coat of white or cream acrylic paint over the front face using a wide flat brush. Let this base coat dry for at least 30 minutes before sketching, as a dry base coat accepts pencil lines better.

Sketch the three shell outlines

Use a soft pencil to lightly sketch a scallop fan, an oval bivalve, and a pointed cone shell across the face of the pumpkin. Vary the sizes slightly so the three shells feel like a natural beach collection. Keep the sketches simple, as fine pencil details will disappear under paint.

Fill each shell with a flat pastel base coat

Paint the first shell in blush, the second in seafoam, and the third in soft lavender. Use a clean flat brush for each color and apply the paint in smooth, even strokes following the overall shell shape. Let each shell dry before applying the stripe details.

Add curved stripe lines

Load a thin liner brush with a slightly deeper tone of the same color and paint curved concentric stripes inside each shell, radiating from the base or apex depending on the shell type. Paint these lines while the base coat is still very slightly soft for a gently blended edge. The depth of the stripe color should be subtle, not strongly contrasting.

Add highlights and fine details

Mix a small amount of white into each shell color and apply a thin highlight stroke along the raised edge or central ridge of each shell with a liner brush. Tiny white dots on the cone shell suggest its natural spotted pattern. Allow the pumpkin to dry completely before sealing.

Seal and display

Apply a clear acrylic sealer spray or brush-on varnish over the entire painted surface and let it cure for at least an hour. Display indoors or in a sheltered outdoor spot. The light pastel palette reads beautifully in natural daylight.
