Tutorial: Making Tiny Mushrooms from Clay

A Fisherman Aesthetic Project with Hand-Painted Glaze

The fisherman aesthetic is all about rustic coastal charm, and nothing captures it quite like sardines. From vintage tins to playful patterns, sardines are making a splash in the DIY world. This shallow clay platter project combines simple slab-building with fine hand-painting to create a functional piece that’s equal parts practical and quirky art.

Whether you’re making it as a serving tray, a decorative wall piece, or a gift for someone who loves nautical style, this sardine platter will bring seaside nostalgia straight into your home.

Materials You’ll Need

• Pottery clay (cone 04–06 earthenware or stoneware)

• Rolling pin or slab roller

• Wooden slats or rulers (to keep thickness even)

• Craft knife or fettling knife

• A ruler and a rounded corner template (or use the printable)

• Slip and scoring tool

• Sponge and water for smoothing

• Underglazes in blue, green, orange, and black

• Clear glaze (glossy or satin)

• Fine detail paint brushes (sizes 0–2 work best)

• Kiln for bisque and glaze firing

Step-by-Step Tutorial

Step 1: Roll the Clay Slab

• Roll your clay slab to about ¼ inch thick using a rolling pin and two guide slats.

• Make sure the slab is even and smooth—compress with a rib tool to reduce warping.

Step 2: Cut the Tray Shape

• Using a ruler and your template, cut out a rectangle with softly rounded corners.

• Gently lift the slab and drape it over a shallow tray mold or slump it into a form (a wooden box lid lined with fabric works in a pinch).

• Smooth the edges with a damp sponge.

Step 3: Add the Rim

• Roll a long coil of clay and flatten it into a strip.

• Attach it around the edge of your slab base, scoring and slipping to secure.

• Blend the seams smoothly for strength.

• Let the tray stiffen to leather-hard.

Step 4: Refine and Dry

• At leather-hard stage, refine the shape—smooth the surface with a damp sponge and compress the rim.

• Carve or lightly impress any border design you want, such as the crisscross pattern from the Craft Gossip template.

• Allow the piece to dry completely until bone dry.

Step 5: Bisque Firing

• Fire your tray in the kiln to bisque temperature (usually cone 04).

• This hardens the piece and prepares the surface for painting.

Step 6: Paint Sardines with Underglaze

• Using a fine paintbrush, carefully paint three sardines in the center of the tray.

• Start with a base coat of blue or grey, then add darker lines for fins and scales.

• Accent with black for eyes and details, and add orange or green banner motifs if desired.

• Keep your strokes light and fluid—this is where the fisherman aesthetic comes alive, with a hand-drawn, imperfect charm.

Step 7: Add Border Details

• Paint the crisscross border pattern around the rim using green or orange underglaze.

• Use a steady hand, but don’t worry about perfection—slight wobbles enhance the handmade look.

Step 8: Clear Glaze Coat

• Once the underglazes are dry, apply 2–3 coats of clear glaze over the entire platter.

• Allow each coat to dry before adding the next.

• Wipe the bottom clean of glaze to prevent sticking in the kiln.

Step 9: Glaze Firing

• Fire the platter to your glaze cone (usually cone 06 for earthenware, cone 6 for stoneware).

• Once cooled, your sardine platter will be glossy, durable, and ready to use.

Styling & Uses

• Use as a serving tray for bread, cheese, or olives.

• Display on a wall as coastal art.

• Pair with your sardine tin clay project for a cohesive fisherman aesthetic collection.

• Gift to a seaside-loving friend—they’ll adore the handmade touch.
