DIY Polymer Clay Sculpting and Modelling

Octopus made with polymer clay mosaic tiles

1. Baking polymer clay

Baking sheets of polymer clay in oven

- Gather your offcuts of Make n Bake Polymer Clay Signature or condition some fresh clay

- Roll the clay into an even sheet around 5mm thick

- Use a clay press or levelling roller to keep the thickness consistent

- Bake the clay following the instructions on the packaging (approx. 30min for every 6mm thickness at 130ºC)

- Allow the clay sheet to cool completely before handling


2. How to transfer image

Tracing outline of octopus onto framed canvas

- Download and print the octopus outline, then shade the backside

- Retrace the outlines to transfer the octopus onto your mosaic surface


3. Polymer clay tiles

Pressing clay tiles onto framed canvas

- Cut the baked clay sheets into small uneven shapes using scissors

- Arrange the clay tiles inside the outline like a puzzle, sticking them down with PVA glue

- Rotate and trim pieces to fit curves and tight angles

- Leave small gaps between tiles as grout will be added later

- Aim for a loose, offset pattern so the octopus stands out


Tip: Avoid cutting your tiles into perfect squares – odd shapes give mosaics their character!


4. Grouting mosaic tile art

Rubbing damp sponge on grouted mosaic

- Once the glue is dry, apply Light Moulding Paste over the tiled surface using a palette knife

- Press the paste gently into the gaps between tiles

- Smooth the surface while keeping tile edges visible

- Once evenly applied, use a damp sponge to gentle wipe away grout residue

- Allow the paste to dry completely


Once your mosaic is all dry, pop it up on the wall for tiled décor on a budget ✅
