Easy Polymer Clay Mini Fish 

This project shows how to make a miniature salmon fish. The finished piece is a small, textured fish with thin translucent fins, a painted body with shading, a glossy eye, and a reflective glaze. Follow the steps in order: shape the base, add surface texture, cut and texture the fins, add the eye and tail, bake, paint, and seal.

Materials and tools

• Salmon cane or a piece of plain white polymer clay (conditioned)
• Needle tools
• Dotting tools
• X‑Acto knife (the video removes the blade for a handle)
• Translucent material (used for thin fin slices)
• Pale yellowish pastel
• Black acrylic paint
• Fimo Deco Gel
• Acrylic paints (white, green and gray shades)
• Pearlex pigment in pearl white (mixed into glaze)
• Gloss/glaze (glass glaze or similar)
• Optional: pearly white acrylic paint or eyeshadow for fins and eye
• Scissors or blade for cutting
• Brushes for painting and mica application

Shaping the base

Step 1 — Form the body

• Take a piece of the salmon cane and use your fingers to give it the basic fish shape.
• If you do not want to use the cane, use a piece of plain white clay and shape it the same way.
• Smooth and refine the shape with your fingers so it reads as a small fish body.

Step 2 — Add small details

• Use needle tools, dotting tools, and an X‑Acto knife to add the small surface details you want on the body.
• Work around the shape to create any sculpted lines or markings before adding texture.

Adding surface texture

Step 1 — Create texture with the X‑Acto handle

• Remove the blade from an X‑Acto knife and use the handle or bladeless tool as a texture tool.
• Press and drag lightly to create the fish’s textured surface, repeating until you are happy with the look.

Make and attach fins

Step 1 — Cut thin fin slices

• Cut very thin slices from the translucent material for the fins.
• Shape each slice into the fin forms you want (pectoral, dorsal, etc.).

Step 2 — Texture the fins

• Use a needle tool to add fine texture lines on each translucent fin piece.
  Save
• Attach the fins to the fish body in the desired positions, blending gently so they sit flush.

Add the tail and eyes

Step 1 — Tail

• The video does not show the tail step in detail but shows the tail present before baking.
• Form and attach a tail so it integrates with the body; ensure it is secured and shaped before proceeding.

Step 2 — Prepare the eye before baking

• Right before baking, apply a pale yellowish pastel where the eye will be.
• Make a small black dot over that pastel with black acrylic paint for the pupil.
• Let the black paint dry, then add a dab of Fimo Deco Gel on top of the eye area.
• These steps are done before baking so the eye detail is set into the piece.

Bake

Step 1 — Bake the piece

• Bake the fish piece after you have added the pastel, black dot, and Fimo Deco Gel on the eye.
• (The video proceeds from this point to post‑bake painting; follow your usual polymer clay baking practice.)

Painting after baking

Step 1 — Base coat and shading

• After baking and cooling, paint the fish with acrylic paint.
• Start with white acrylic paint on the entire fish except the fins.
  Save
• Add shading using green and gray shades to build depth and realism.

Step 2 — Eye and fin highlights

• For the eye and fins you can use a pearly white acrylic paint or a pearly eyeshadow to add subtle highlights if desired.

Glaze and finish

Step 1 — Prepare the glaze

• Mix Pearlex pigment in pearl white into your glaze to give the body a more reflective look.
• For fins and eye highlights, the creator used plain glass glaze without pigment.

Step 2 — Seal the piece

• Brush the pearl‑pigment glaze over the fish body for a reflective finish.
• Apply plain glaze to the fins and eye as shown to finish the look.
• Allow the glaze to dry fully.

Tips

• Use very thin translucent slices for delicate, natural-looking fins.
• The X‑Acto handle (blade removed) makes a good texture tool for fine surface marks.
• Apply the eye details before baking and seal with Deco Gel so the eye reads well after baking.
• Mixing pearlex into the glaze gives a subtle reflective sheen for a lifelike finish.
