## Skills you'll need (section 03)

| Fact used | Source |
|---|---|
| Skills (this experience): Hand-modelling a small Ganesha from shadu (natural) clay: base, body, head, trunk and ears; Keeping clay workable: kneading, joining pieces, slow drying without cracks; Eco rules: natural colours, no Plaster of Paris (PoP), plastic or thermocol; home or artificial-pond immersion | Skills research, checked 2026-10-04 (IST) |
| Difficulty (our estimate): Beginner; prep time (our estimate): 30 minutes reading plus 1–2 practice sessions with any clay. Difficulty and prep time are Curiosta editorial estimates for a first-timer, not organiser figures. | Curiosta editorial estimate |
| Refresher, practice and safety steps: Knead the clay well to push out air and get an even, smooth texture; air pockets cause cracks. / Build from the bottom up: a stable seat or base, then the body and legs, then the head; keep the idol small enough to dry evenly. / Join parts by roughening (scoring) both surfaces and adding a little wet clay as glue; smooth the seam with a damp finger. / Cover clay you are not using with a damp cloth so it doesn't dry out mid-session. / Let the idol dry slowly in shade, not direct sun or a fan, to avoid cracking. / If you colour it, use natural or non-toxic water-based colours; skip glitter, plastic and thermocol decorations, as the CPCB idol guidelines advise. / Plan the immersion: a bucket at home or a civic artificial pond, then reuse the dissolved clay in plants or soil. / Try any natural clay (pottery clay or shadu from a local supplier) at home: practise a seat, a pot-bellied body and a trunk. / Practise scoring and joining two clay pieces, then let them dry to see whether the join cracks. / Look for a civic workshop in your city before Ganeshotsav (organisers: Unconfirmed: no official source; check your city corporation's own notices). / Use natural clay and non-toxic colours only; avoid PoP and chemical paints. / Immerse at home or in a designated artificial pond, not in rivers, lakes or the sea, unless local rules allow it. / Wash hands after handling clay and any colours. | Our summary of the resources below |
