Imperfections in wood can make for the loveliest carvings

I am married to a wood snob. When we bought our house in 1999, my husband insisted that all the shelves (he is an antiquarian book dealer, so there are miles of them) should be made of ‘real’ wood, with not an inch of Medium Density Fibreboard. The price made me squeal. But a quarter of a century on, while friends’ MDF shelving droops like cables between telegraph poles, ours remains beautifully strong and straight.

Callum Robinson would understand why this matters. A master woodcarver and cabinetmaker, plying his trade from a workshop in Scotland (location vague – ‘in a forest beside a loch nestled in the Scottish hills’), he is such a perfectionist that if one of his team used the wrong screw on the back of a bedside table, where nobody would ever see it, he would whip it straight out.
