How We Choose Our Materials. The Decisions Behind Every Nithyam Calendar.

Every material decision in a handmade object is a values decision. What we build with, the finish we apply, the way we treat each surface before it leaves our studio - each of these choices reflects what we believe the object should be and how long we expect it to last. This article explains those choices in detail.

The board of every Nithyam calendar is made from 6mm plywood. We made this choice deliberately, and we want to be transparent about why. Plywood's cross-layered construction gives it a dimensional stability that solid wood struggles to match, especially in Indian homes, where humidity swings significantly between seasons. Each layer runs its grain perpendicular to the one beneath it, which cancels out the expansion and contraction that causes warping and cracking in solid boards. At 6mm, the board is thick enough to stay rigid and hold its shape under daily handling, but light enough to mount easily and comfortably on a wall. It is the correct material for an object designed to last a lifetime.

The knobs are made from recycled plastic bottle caps. This was a practical decision as much as a sustainability one. Caps are manufactured to a consistent size and shape, which means every knob on every board sits, fits, and holds the same way - there is no variation to correct for, the way there would be with a hand-shaped material. They do not absorb moisture, they do not swell or shrink with the seasons, and they hold up to years of being touched, turned, and handled every single day. Giving a waste material a permanent, functional second life on an object meant to last for years felt like the right use for it.

The markers are solid wooden rings, turned on a lathe in our workshop and fitted to sit around the knobs. This is where the mechanism has to be exact. The inner diameter of each ring has to be precise enough to hold firmly on the knob without wobbling, but not so tight that the ring resists being turned by hand each morning. Getting that balance right took several rounds of testing across different ring diameters before we arrived at a fit that felt both secure and effortless. After turning, each ring is sanded through multiple grit levels to remove any roughness at the edge, then finished with matte paint. Rings that don't meet our standard for smoothness or coverage are repainted or discarded.

The finish across the board and the rings is a matte paint, applied in our studio. We chose matte over gloss because gloss shows fingerprints and dust in a way that matte does not. A calendar that is touched every morning needs a finish that ages gracefully with daily contact, rather than one that shows every interaction as a mark.

For labelling the days, dates, and months, we use high-quality print vinyl stickers rather than hand-painted or hand-lettered script. This is not a shortcut - it is a precision decision. Printed stickers give us sharp, legible, perfectly consistent text on every single calendar we make, and a finish that resists fading and wear far better than paint applied by hand ever could.

None of these decisions are visible when you look at the calendar on your wall. They are visible over time - in the way the board holds its shape through changing seasons, in the way the rings keep turning smoothly morning after morning, in the way the object continues to look considered rather than tired.

That is what material decisions are for. Not to be noticed, but to be trusted.
