Maharashtra SSC Decorative Pieces from Waste Divyang cheat sheet

PPE rule for waste handling: cut-resistant gloves for wire, glass, and sheet metal; nitrile gloves for adhesives and paints; safety glasses whenever cutting, drilling, or sanding; dust mask (N95 or better) for sawdust, thermocol dust, and sanding residue.

Eye protection is mandatory within 1 m of any rotating tool (drill, grinder, buffing wheel); loose sleeves, scarves, and long hair must be tied back before the machine starts.

Electrical rule: use only tools with intact 3-pin plugs and earth connection; never run a power tool from a wet floor; unplug before changing blades, bits, or discs.

Ventilation decision rule: solvent-based paints, thinner, Fevicol-type adhesives, and spray work require open windows plus cross-ventilation; confined rooms without airflow are a stop-work condition.

Workspace zoning: separate cutting zone, assembly zone, finishing/painting zone, and storage zone; keep a 1 m clear walkway and never store sharp offcuts on the floor.

Fire rule: keep a dry-powder or CO2 extinguisher within reach of the painting area; no open flame, incense, or smoking near thinners, spray cans, or solvent rags.

First aid minimum: running water for 15 minutes for chemical eye splash, direct pressure for cuts, and a written emergency contact displayed at the workspace entrance.

Manual handling rule: lift offcuts and boards with knees bent and load close to the body; two-person lift for any piece above roughly 15 kg or longer than 1.5 m.

Segregate at source into four streams: paper/cardboard, plastics (bottles, caps, wrappers, thermocol separately), textiles (cloth, jute, denim), and rigid/inorganic (glass, metal, ceramic, e-waste).

Cleanliness test before acceptance: a material is usable only if free of food residue, oil, and moisture; greasy plastic or food-soiled card is rejected or washed before storage.

Material property mapping: PET bottles give transparent flexible sheet when heat-shrunk; HDPE caps give rigid coloured discs; cardboard gives flat structural panels; jute gives high-tensile fibre for weaving.

Glass waste is sorted by colour (clear, green, brown) because mixing colours limits decorative use; edges are treated as sharp until ground or taped.

E-waste rule: circuit boards, wires, and batteries are handled as separate hazardous stream; batteries never go into general craft stock because of leakage risk.

Metal identification by simple tests: magnet attraction indicates iron/steel; non-magnetic shiny light pieces are usually aluminium; avoid galvanised sheet for food-contact items.

Storage rule: label each bin by material and keep dry storage off the floor on pallets or shelves; moisture causes mould in paper and jute within days.

Quantity check for planning: weigh or count each stream before design so the piece is sized to available material, not to an assumed supply.

Washing sequence for bottles and plastic: remove label and cap, soak in warm water with a few drops of detergent, scrub adhesive residue, rinse twice, and air-dry fully upside down for 24 hours.

Adhesive residue removal: vegetable oil or warm soapy water for label gum on glass and plastic; never use thinner on PET because it clouds and weakens the plastic.

Cardboard flattening: open flaps, remove tape and staples, press flat under weight for 24 hours; moisture content must be low or the panel warps after gluing.

Thermocol cutting rule: cut with a hot-wire cutter outdoors or with a mask; snapping and sawing produce fine dust that is difficult to contain.

Jute and cloth preparation: wash, dry, then comb or iron flat; frayed edges are sealed with a thin white glue line or a zig-zag stitch before use.

Glass preparation: wash, dry, then dull sharp edges with wet abrasive paper or a diamond file under water to control dust; never dry-sand glass edges.

Metal preparation: remove rust with abrasive paper or vinegar soak, then degrease with detergent before priming; paint over rust fails within weeks.

Drying standard for all materials: no visible moisture, no cool-to-touch feel, and no damp smell before any glue or paint is applied.

Design sequence: need and user, function, size, material available, sketch, dimensions, cutting list, then prototype - never start cutting before the cutting list is written.

Scale rule: draw the sketch at 1:1 for pieces up to 30 cm; use 1:2 or 1:5 for larger items and mark the scale on the sheet.

Orthographic minimum for a decorative piece: front view, side view, top view, plus one isometric or perspective sketch for client presentation.

Dimensioning rule: every sketch carries overall height, width, depth, and material thickness; internal part sizes come from the cutting list.

Ergonomic sizing: photo frame border 2–4 cm, wall hanging length matched to eye level (centre roughly 150 cm from floor), pen stand height 8–12 cm.

Material-driven design rule: choose the joint and finish after confirming the material; cardboard suits slot-and-tab joints, jute suits weaving and wrapping, glass suits edge-protected framing.

Design for Divyang accessibility: prefer large-grip tools, clamped workpieces, and modular parts that can be assembled single-handed; avoid designs needing continuous two-hand pressure.

Waste-minimising layout: nest shapes on the sheet so offcut is under 20 percent; draw the layout on the sheet before cutting to verify fit.

Cutting tool by material: scissors or craft knife for paper and cloth, fine-tooth saw or hot wire for thermocol, tin snips for sheet metal, tile nippers for glass mosaic.

Craft knife rule: cut in multiple light passes along a steel ruler, blade pointing away from the body, and always cut on a self-healing mat.

Drill rule for plastic and acrylic: start with a pilot hole, run at low speed, and back the workpiece with scrap to prevent cracking at breakthrough.

Adhesive selection: white glue (PVA) for paper, card, and wood; hot glue for quick tacking of jute, thermocol, and plastic; epoxy or cyanoacrylate for glass, metal, and load-bearing joints.

Hot glue caution: thermocol melts above roughly 70–80 degrees Celsius, so keep the nozzle moving and apply thin lines rather than a heavy blob.

Mechanical joints: slot-and-tab for cardboard, lap joint for sheet metal with rivets, wire wrap plus glue for jute armatures, and stitched seam for cloth.

Clamping rule: hold glued joints under weight or clamps for the full open time (PVA typically 30–60 minutes, full strength in 24 hours).

Glass and mirror assembly: mount in a frame or on a backing board with adhesive pads; glass is never drilled or joined edge-to-edge with glue alone.

Surface preparation order: sand (coarse to fine), dust off, prime, then paint; skipping the dust-off step causes flaking and visible grain in the finish.

Primer rule: use primer on metal, raw wood, and cardboard before topcoat; acrylic paint on unprimed cardboard soaks in and looks patchy.

Paint choice: acrylic emulsion for paper, card, and thermocol; enamel for metal and sealed wood; fabric colours for cloth; always test on an offcut first.

Layering rule: apply two thin coats rather than one thick coat; recoat only after the first is touch-dry, otherwise the film wrinkles.

Decoupage: brush a thin glue layer, press paper flat from the centre outward to push out air, then seal with two clear coats.

Sealant choice: clear acrylic varnish for indoor pieces, polyurethane or exterior varnish for outdoor pieces; sealant also protects paint from moisture and handling.

Mosaic and embellishment: fix tiles or beads with strong adhesive, leave gaps, grout after 24 hours, then wipe the surface before the grout hardens.

Colour scheme rule: limit a piece to two main colours plus one accent, and keep the accent under roughly 10 percent of the visible area.

Joint strength test: a finished joint must hold the piece's own weight plus a light pull by hand without movement; any creak or gap is a rework signal.

Stability check: place the piece on a flat surface and press each top corner in turn; rocking or tipping indicates an uneven base or off-centre mass.

Edge and surface standard: no sharp edge, burr, or exposed wire end; edges are rounded or taped, and all fixing points sit flush.

Moisture resistance: outdoor or washable items need a sealed surface and water-resistant adhesive; unsealed cardboard loses strength quickly in humid air.

Finish inspection under raking light: hold a light at a low angle to reveal sanding scratches, drips, dust nibs, and missed patches.

Load and use test: simulate the intended use (hang a frame, place a pen in the stand) and confirm no deformation after 24 hours.

Checklist before dispatch: dimensions match the drawing, colour is even, no glue strings, hardware is tight, and the base is felted or padded.

Tolerance rule: visible gaps at joints are kept under about 1 mm; larger gaps are filled or the part is recut.

Waste hierarchy applied to craft: refuse unnecessary material, reduce offcut, reuse offcuts as small parts, recycle the rest, and dispose only as a last step.

Offcut rule: pieces above roughly 5 cm are stored by material in labelled scrap boxes for future small items such as beads, tiles, and tags.

Adhesive and paint disposal: never pour thinner or paint residue down a drain; collect in a sealed container and hand to the local waste collection point.

Low-impact choices: water-based adhesives and paints over solvent-based; natural fibres (jute, cotton, coir) over virgin plastic sheet where strength allows.

Energy rule: switch off drills, glue guns, and lights when idle; batch cutting and painting jobs to reduce tool run time.

Repair-first design: make joints and fixings accessible so a broken piece can be repaired rather than discarded.

Buyer communication: state the recycled content and material origin on the label; this supports the eco claim and builds trust.

Local sourcing: collect waste from nearby homes, shops, and tailoring units to cut transport and keep a steady supply.

Costing formula: total cost = material cost + labour (hours x hourly rate) + overhead (power, rent share, tool wear) + packaging; selling price = total cost + margin.

Pricing rule: a common small-business benchmark is material cost no more than about 30–40 percent of selling price, so labour and overhead are actually covered.

Waste-material costing: collected waste carries near-zero purchase cost but still carries processing labour (cleaning, sorting, drying), which must be counted.

Packaging rule: cushion the piece on all sides with paper or card offcut, keep glass and ceramics double-boxed, and mark the box 'fragile, this side up'.

Label content: product name, material used, care instructions, maker name, and price; a care line such as 'wipe with dry cloth, keep away from water' prevents complaints.

Photography for sale: plain light background, natural light, one full view plus one close-up of detail, and a scale reference so buyers judge size correctly.

Presentation at exhibition: group items by theme, place price tags facing the viewer, and keep a printed catalogue with material and price details.

Break-even check: break-even units = fixed cost divided by (selling price minus variable cost per unit); this tells the minimum volume to avoid loss.

Enterprise forms: sole proprietorship (simplest, single owner), self-help group or cooperative (shared cost and risk), and micro-enterprise registered for scheme benefits.

Registration path in Maharashtra: Udyam (MSME) registration is free and online; it opens access to subsidy, loan, and tender benefits.

Finance sources to check: bank loan under schemes for persons with disabilities with concessional interest, National Handicapped Finance and Development Corporation support, and district industry centre guidance.

Working capital rule: keep a cash reserve covering roughly 2–3 months of material and overhead so one slow month does not stop production.

Record keeping minimum: a daily production log, a purchase and sales register, and a receipt book; these are required for loan applications and tax filing.

Marketing channels: local exhibitions and fairs, school and office bulk orders, social media pages with photographs, and tie-ups with gift shops.

Accessible workplace: fixed-height work tables, clamp-on tools, good task lighting, and stored items within easy reach reduce fatigue and raise output.

Growth path: standardise the best-selling 3–5 designs first, then train helpers and batch-produce rather than making each piece unique.
