Create a papier-mache hanging mobile of planets
A solar-system mobile turns recycled paper, simple shapes and a little string into a decoration that keeps changing as it turns. The planets can sit at different heights, with Jupiter broad and striped, Saturn wearing a ring and Earth carrying blue-and-green patches. It is an approachable project for families, beginners and anyone who enjoys making something playful from inexpensive materials.
Choose papier-mache strips over papier-mache pulp for easier control. Balloons or lightweight paper balls make useful forms, while PVA glue holds the layers together. Each planet needs several drying breaks, so the project works well across a weekend or a school holiday. The finished mobile works especially well in a child’s room, play area or party space.
Choose a layout that suits your room
Sketch the arrangement before covering any forms. A mobile measuring 50–60 centimetres across suits most indoor spaces, including compact Sydney and Melbourne apartments, while a smaller version may be better for a Brisbane courtyard or courtyard-facing room. Measure the ceiling area rather than relying on a picture online, and leave enough clearance for the planets to turn freely.
Keep the scale artistic rather than scientifically accurate. Jupiter can be twice the size of Earth, and the other planets can be grouped loosely by colour. Plan one large anchor planet near the centre, then place smaller worlds around it. This arrangement keeps the mobile balanced and gives the hanging threads enough room to remain separate.
Gather materials from familiar Australian shops
Paper, glue and paint are easy to find at Bunnings, Officeworks, supermarkets and independent craft shops across Australia. Reused envelopes, kraft wrapping paper and clean newspaper can replace purchased papier-mache material. Collect a few wooden dowels, cotton thread, masking tape and a small brush alongside water-based acrylic paints in black, white and a useful range of earthy colours.
A basic shopping list keeps the project economical and reduces extra trips to the craft market:
- Save clean newspaper, tissue paper or kraft paper for covering the planet forms.
- Pick up PVA craft glue, a flat brush and a small bowl for mixing.
- Gather paper balls or balloons, wooden dowels and strong cotton thread.
- Choose water-based acrylic paint and a soft brush suitable for fine details.
Before buying extras, browse paper craft inspiration for complementary ideas such as card moons, folded stars and recycled decorations. Protect a work surface with newspaper, and tear strips by hand rather than cutting every piece; uneven edges create a smoother transition between layers than identical machine-cut strips.
Shape the planets and compare sizes
Make a base layer from tissue paper or smooth kraft paper, then apply three or four papier-mache layers. Overlap each strip by about half its width and brush glue lightly so the paper does not buckle. Let each planet become firm before adding the next layer, then allow the final coat to dry completely before painting.
Use this size comparison as a guide, adjusting the measurements to suit your mobile:
| Planet | Suggested diameter | Best form | Main detail |
|---|---|---|---|
| Mercury | 7 cm | Paper ball | Grey craters |
| Venus | 9 cm | Small balloon | Cream cloud bands |
| Earth | 11 cm | Paper ball | Blue oceans and green land |
| Mars | 8 cm | Paper ball | Rust colour and pale ice cap |
| Jupiter | 17 cm | Balloon | Wide brown and cream stripes |
| Saturn | 14 cm | Paper ball | Pale bands and a paper ring |
| Uranus | 12 cm | Paper ball | Soft blue with a light ring |
| Neptune | 12 cm | Paper ball | Deep blue and white cloud shapes |
Torn newspaper produces a textured surface that suits Mercury, Mars and Jupiter. Smooth paper strips create a neater finish for Earth, Venus and Saturn. Form Saturn’s ring separately from lightweight card, paint both sides and attach it while the planet is still slightly damp so the edges settle into place.
Paint a playful solar system
Apply a thin base coat first, using a light colour for planets with stripes and allowing it to dry before adding the darker marks. Earth works well with irregular green continents over a blue background, while Jupiter benefits from broad, uneven bands. Small dots and short brushstrokes can suggest craters, oceans and cloud systems without turning the project into a detailed model.
Use water-based acrylics available from Australian art suppliers, and avoid solvent-based sprays or loose glitter around children. A water-based clear coat can protect the colours, although it should be applied lightly in a ventilated room. Colours may fade near a north-facing window, where Australian sunlight can be intense, so place the mobile on a side wall or away from direct glass.
Balance, assemble and hang the mobile
Tie two wooden dowels together at their centres with several tight turns of thread. This cross becomes the mobile’s frame. Attach cotton thread to each planet using a small dab of glue inside the knot, then secure the threads at different points along the dowels. Vary their lengths so the planets appear to float through space rather than forming one crowded row.
Check the mobile before attaching it to the ceiling:
- Make sure every painted planet is completely dry before threading.
- Hang heavier planets opposite one another to balance the frame.
- Hold the central loop and move attachment points until the cross stays level.
- Add the final ceiling string only after the planets hang freely.
An adult should install a suitable ceiling hook, using the correct fixings for the wall or joist type. Keep the mobile well away from cots, playpens and open windows, since swinging planets and loose threads can pose a hazard. In humid coastal homes, allow the papier-mache to dry indoors for an extra day so trapped moisture does not soften the paper.
If you plan to sell finished mobiles at a school fete or makers’ market, the Australian Consumer Law requires commercial goods to be safe and accurately described. Provide intended use, age guidance, material details and care instructions, and do not market a decoration with detachable small parts as a toy for children under three. Renters and apartment residents should also check with their landlord or body corporate before drilling.
Display, care and celebrate your work
Hang the mobile where people can see it from different angles, such as beside a reading corner, above a play table or near a party display. Indoors, it will respond to gentle air movement; on a covered verandah, check that wind cannot tangle the threads. Adjust the lowest planets until every silhouette remains visible from the main viewing position.
Dust the planets gently with a soft, dry brush rather than wiping them with a damp cloth. If the colours dull over time, add another thin protective coat in a well-ventilated space. Keep the mobile away from heaters and kitchen steam, and bring it indoors during very wet weather.
Your finished planets also become useful props for a space-themed birthday party, classroom display or seasonal gathering. Save the smallest offcuts for paper moons and stars, then share the completed mobile with a local craft group or maker community. Create your own small universe from paper, paint and a few pieces of string, and let the planets turn the everyday into something worth looking up to.
