10 ideas for objects to create with self-hardening clay:

1. A hand-shaped bowl

Ultra symbolic and easy to make, the hand bowl is perfect as a pocket emptier or jewelry holder. Simply place your hand on the rolled-out clay, trace the outline, cut, and gently shape the palm. Let it dry on an upturned bowl to create the shape.

2. A shell jewelry holder

With a simple shell cutter or freehand, you can create a pretty ring or earring holder. Pastel paint works very well here. Add a slight pearlescent effect with an iridescent varnish.

3. Candlesticks or tealight holders

Shape an open cylinder using a tea light mold. For an organic effect, pinch the edges irregularly. You can also create a marbled effect by mixing two clays.

4. Pendants and keychains

Perfect for kids or small handmade gifts. Use a cookie cutter, cut a hole with a straw, paint, and add a tie. Lettering, symbols, hearts, or flowers work well.

5. A single-flower vase

Create a small, tall, narrow cylinder. It won't be airtight, but it's perfect for dried flowers. Texture the outside with fabric or a blade to create a sculptural effect.

6. Mini pencil holders

Ideal for a creative office, you can even customize the edges into waves, flowers, or geometric patterns. Paint the inside and leave the outside unfinished for a contrasting texture and color.

7. Decorative figurines

Small animals, abstract bodies, minimalist faces... It's time to play with volume. For fine details, wait until the paint is half-dry for greater stability. Our Joy kit includes mini tools perfect for sculpting.

8. Personalized magnets

Flatten simple shapes (hearts, leaves, moons, etc.), pierce the back, or stick a magnet on once dry. A great idea for fridge decoration or a small gift.

9. Place cards or napkin rings

For a unique table setting, you can create personalized name tags or rings with fingerprints, letters, or symbols. Let your heart speak.

10. A wall hanging

String together several perforated shapes, then connect them with string or gold thread. The effect is light, poetic, and very decorative.

Tips & Mistakes to Avoid in Pottery

When you're first starting out with self-hardening clay, there are a few practical tips to help you avoid disappointment. Proper preparation and proper drying make all the difference in the durability and longevity of your creations.

• Dry slowly and on fabric to avoid cracking (24–48 hours recommended). Fabric absorbs moisture gently and avoids direct contact with hard surfaces.
• Always wait until the clay is completely dry before sanding, painting or varnishing , otherwise you risk weakening the object.
• Never immerse finished objects: clay remains porous , even once varnished. Prolonged contact with water could damage them.
