Cat house or scratching post
Domestic cats have always sought dens: enclosed, dark spaces with a single entrance, like the holes where their ancestors hid from predators. Cardboard fits perfectly because it insulates temperature, absorbs the animal's scent, and its corrugated surface, when exposed in layers, invites claws — the cat scratches to mark territory and wear down the sheath of its claws.
- 2 to 4 sturdy cardboard boxes one large for the house, others to cut layers from
- Utility knife or strong scissors
- Ruler and pencil
Dyeing sisal cords and twine
Sisal is pure plant fiber, full of natural tannins — which means it reacts with iron mordant with almost no prep, turning an aged leather or burnt straw tone. Macramé and basket artisans discovered this as a cheap alternative to industrially dyed cords, which cost far more. The result has that feel of a piece found at an old flea market.
- Iron mordant solution
- Sisal or jute cord, or natural twine
- Basin or jar
Picnic spice shakers
Travelers and campers have always adapted everyday containers to carry the essentials, and multifunctional camping salt shakers inspired this homemade version. It works because the plastic cup is light, and each one becomes a sealed compartment with a screw or flip top, keeping salt, pepper, and herbs dry until it's time to use them.
- 3 or 4 rigid plastic cups of the same size
- Screw-on plastic lids from small jars or strong tape
- Craft knife or scissors
Small candle holder
Dark glass pharmacy bottles have always carried an air of old-time alchemy — and it pairs perfectly with the warm glow of a candle. Thick glass conducts heat slowly, which keeps the flame steady and protects it from drafts, working like a small amber or brown lamp.
- A glass medicine bottle, well cleaned and label-free
- A small votive candle or a ready-made jar candle that fits inside
- Fine sand or coarse salt a base layer, optional
Homemade spice holder
Before standardized store-bought jars, home kitchens lived on repurposed bottles — from jams, jellies, and pharmacies — to store herbs and spices. It works because glass is impermeable and doesn't exchange aroma or moisture with the contents, protecting the seasoning from humidity and light when kept in the cupboard.
- A glass medicine bottle, residue-free, with its lid
- Boiling water and detergent
- A label, adhesive tape, or a strip of paper
Paperweight and desk organizer
Glass has always been paper's companion: before modern staplers, scribes and cartographers used heavy glass blocks to keep maps and documents stretched flat on the table. It works because glass is dense and smooth — the weight distributed across the base presses evenly without crushing, and the transparency lets you see what's underneath.
- Glass jars with various openings, clean and dry
- Fine sand, pebbles, or coarse salt for weight
- Fabric scraps or cotton cord twine, t-shirt yarn
Donation for parts
Workshops and technical schools have always lived on donated devices: a phone that no longer turns on holds a screen, cameras, tiny screws and boards that still work. Before thinking about repairing it, you need to understand the structure: a swollen battery is an internal pressure problem — the gas released by chemical degradation pushes the casing from the inside out.
- The iPhone with the swollen battery
- A sturdy, non-flammable box or container a metal tin, ceramic pot
- Wide adhesive tape masking tape or packing tape
Picnic spice holder
Salt, pepper and herbs in small doses have always accompanied travelers and fishermen, who carried condiments in glass jars attached to wooden boxes. The principle is simple: portioning out the seasoning before leaving home cuts weight and keeps everything from spilling in the backpack.
- Disposable cups with lids or cups without lids
- Scissors and sturdy adhesive tape
- A scrap of fabric or felt
Glittering mosaic
Mosaic is one of the oldest decorative techniques in the world, made by Romans and Byzantines with stone and glass shards fitted one by one. The CD brings this tradition into modern days: its recorded side reflects light because it has an ultra-thin metallic layer that splits the rainbow's tones into tiny sparkling bits.
- 2 or 3 CDs that have already served their purpose
- Sturdy scissors or cutting pliers
- A base: flower pot, small mirror, wooden box or picture frame
Mirrored coaster
Before plastic and paper, families cut cork and thin wood to protect tables from the moisture of cups. The CD naturally fills this role: it is flat, exactly the size of a cup base, and its metallic coating resists water well — it just needs a soft covering on the front and back.
- 1 CD per coaster
- Scrap of felt, cork or cotton fabric
- Scissors and white glue or fabric glue
Party-style disc ball
In the 1970s, dance floors spun under balls covered in mirrors, which fragmented light into thousands of glittering dots. The CD has the same magic: its recorded surface works as a diffraction grating, breaking light into rainbows. With dozens of cut discs, you recreate this effect with what you already have at home.
- 10 to 15 old CDs or DVDs
- Strong scissors or cutting pliers
- Styrofoam ball, papier-mâché ball or light plastic ball 10 to 20 cm
Wall clock face
The vinyl record became a classic of handmade wall clocks, and the CD follows the same logic in compact form: it is round, rigid, with a ready-made center hole — exactly where the clock mechanism fits. The reflective surface still bounces the room's light, giving the clock a discreet shimmer of movement.
- 1 CD or DVD in good condition
- Quartz clock mechanism kit with hands, sold at hardware and craft stores
- Hot glue or epoxy glue
Circular loom piece
- 1 old CD preferably without deep scratches on the back face - Cotton yarn, string or t-shirt yarn - Scissors - Measuring tape or ruler - Crochet hook or thick yarn needle for finishing - Textile pen optional, for marking pairs - Beads or small beads optional
- 1 old CD preferably without deep scratches on the back face
- Cotton yarn, string or t-shirt yarn
- Scissors
Spinning wind mobile
Mobiles became famous with modernist sculptors, who discovered that shapes suspended on threads create continuous movement with the slightest breeze. The CD is perfect for this: its evenly distributed weight and its reflective surface make each piece spin and scatter light reflections around the room.
- 4 to 6 old CDs
- Nylon thread or thin fishing line
- Thick heated needle for piercing or a small drill
Table mirror
Small mirrors on supporting bases have accompanied dressing tables since the perfume bottles of the last century, bringing depth and luminosity to dark corners. The CD's recorded surface reflects like a dark mirror, and the rainbow sheen of the protective layer gives a retro air that matches vintage decor.
- 1 CD or DVD in good condition no deep scratches on the shiny part
- A jar lid, thick cork or small wooden base
- Strong glue epoxy or hot glue
Rainbow experiment
Diffraction is the phenomenon in which light unfolds when it meets microscopic grooves, and CDs are ready-made diffraction tools: their recorded surface has ultra-fine tracks spaced little more than a micrometer apart. When white light hits these grooves, each color reflects at a slightly different angle — the same principle as retroreflective "cat's eyes," now revealing the visible spectrum in your hand.
- 1 or 2 old CDs data or music; the shinier the face, the better
- Strong phone flashlight or a plug-in flashlight
- Pencil, pen or barbecue skewer
Music box
Music boxes were born in 18th-century Switzerland, when watchmakers discovered that a pinned cylinder rotating over metal teeth produces melodies. The CD, with its reflective surface and rigid plastic, works as a surprising resonator: sound strikes the surface and vibrates the trapped air, amplifying the notes like a small speaker cabinet.
- 1 old CD
- Simple music box movement recoverable from a toy or bought cheaply, with cylinder and tee…
- Hot glue or contact cement
Bells and sound shakers
Bells have existed since antiquity and work on a simple principle: when a rigid body vibrates, it pushes the air in waves — the larger and thinner the material, the deeper the sound. CDs cut into strips or pieces vibrate like small metal blades, and stacked loosely they create the shaker. It's the same physics of wind chimes and garden carillons, now with shiny acrylic.
- 3 to 5 old CDs
- Strong scissors or cutting pliers CDs cut well with care
- Nylon thread, thick string or thin wire
Rope-wrapped tire ottoman
Covering rigid structures with woven fibers is an old craft technique used by artisans who needed sturdy seats without spending on upholstery. The tire works because its steel-reinforced rubber carcass distributes the sitter's weight without deforming, and the wrapped rope creates a firm, comfortable surface on top.
- 1 clean, dry tire a mid-size one, like a 175, is the most comfortable
- Sisal rope or thick cotton cord about 50 to 80 meters, 6 to 10 mm
- Hot glue or contact cement
Hanging tire swing
The tire swing was born in the countryside, where no family would let go of a still-whole tire: they hung it from a tree and done — fun guaranteed for decades. It works because the rubber tire distributes the sitter's weight across its entire circular structure, and the rope knot at the top creates a single pivot point that swings smoothly without locking.
- 1 car tire with no deep cuts in the tread
- Thick nylon or sisal rope at least 10 mm, about 4 meters
- A thick horizontal branch or a sturdy beam on the roof
Tire coffee table with top
Turning tires into furniture became hugely popular in sustainable furniture projects because rubber has ideal compression and elasticity: it carries load without deforming and absorbs unevenness in the floor. The structural key is balance — the top needs to be wider than the tire so the center of gravity stays low and the table does not tip over.
- 1 or 2 car tires of the same size
- A round wood top or pallet wood cut into a circle, about 20 cm wider than the tire
- Contact cement or screws with wall anchors
Rope rug wrapped around a tire
Wrapping rope around circular structures is an ancient basketry technique, adapted by artisans who discovered in the tire the perfect base for floor rugs. It works because the tire gives firmness and the rope, wrapped in a very tight spiral, forms a dense, soft surface that withstands footsteps for years.
- One thin tire from a small car, clean and dry
- Sisal or jute rope or t-shirt yarn — about 50 to 80 meters
- Hot glue or contact cement
Cat house or scratching post
Cardboard pressed in spiral layers is surprisingly resistant to compression — that's why factories use it to pack heavy loads. Cats love the texture for sharpening their claws, and crafters have discovered that whole tubes, joined together, become sturdy structures that hold the weight of a cat lying on them.
- A cardboard tube a rolling tube; the thicker, the better
- A saw or a strong craft knife with a fresh blade
- White glue or hot glue in abundance
Hanging vertical garden
Vertical gardens were born out of necessity for people with little space — balconies and walls became gardens in cities all over the world. It works because most small herbs and vegetables have shallow roots: they don't need depth, but rather light and well-distributed watering, which the vertical position favors.
- 3 or 4 water jugs of the same size, clean
- Strong craft knife
- Sisal rope or thick, sturdy string
Styled bucket
Before buying a new planter, folks in the countryside were already turning paint cans and buckets into benches, watering cans and cachepots — the dried paint inside became part of the décor. It works because the plastic or metal paint packaging is made to withstand strong chemicals, so it holds up to water, soil and sun without degrading.
- Paint bucket with dried paint residue
- Medium-grit sandpaper 120 grit
- Damp cloth
Omelets and scrambled eggs
Mixing dried herbs into eggs is an old Middle Eastern custom, where za'atar has accompanied breakfast for centuries alongside olive oil and bread. It works because the essential oils in oregano and thyme release their aroma with heat, and the egg's fat carries those flavors like no other ingredient could.
- 2 to 3 eggs
- 1 teaspoon of za'atar more or less to taste
- Salt and olive oil
A za'atar herb garden
Traditional za'atar comes from three plants grown together for centuries in the Mediterranean and Middle East: oregano, thyme, and marjoram or mint. All of them are perennials that love sun and well-drained soil — which is why they get along so well in the same pot, sharing the same water and light needs.
- Pots or cans with holes in the bottom at least 6 inches deep
- Regular potting soil mixed with a bit of coarse sand or gravel to drain the water
- Seeds or seedlings of oregano, thyme, and mint
Your own za'atar blend
Before it became a store-bought seasoning, za'atar was made at home by families who dried their own herbs on the roof and ground them fresh. It works because the aroma of these leaves lives in volatile essential oils: when you dry and mix them in your own kitchen, those oils are far more present than in any package that's been open for months.
- Dried oregano, thyme, and mint leaves from your garden or store-bought
- White sesame seeds
- Coarse salt or sea salt optional
Fragrant herb sachets
Herb sachets have accompanied humanity for centuries: they were kept in drawers and closets to scent clothes and keep moths away. It works because the herbs release volatile essential oils, which spread through the enclosed air inside the porous fabric.
- Za'atar the blend is already fragrant on its own, with thyme, oregano, and sumac
- Scraps of lightweight fabric, like cotton or knit from an old T-shirt
- Needle and thread, or fabric glue
