Keep a Christmas ideas list from February onwards

February is an odd month to think about Christmas, which is why it works. The shops are clearing stock, so you can see what things really cost. And you have just been through a Christmas, so you remember exactly which gift you hoped for and did not get. Ten months of noticing beats ten minutes of guessing on the sofa in December.

A list kept over a year also shows how your interests move. The thing you try in February might be a settled hobby by November, and by then you will know precisely which kit to put on your Christmas list, rather than writing "something for the bike" and hoping.

Decide on a few groups before you add anything

Keep the list in sections from the start: house, hobbies, small treats, books and music, things to do. Five headings is plenty. Buyers find their way round a structured list far faster than a jumble of forty items, and you notice the gaps. A list with twelve books and nothing for the kitchen is telling you something.

Mix precise entries with looser ones. "Sony WH-1000XM5 in black" is useful to a buyer. "Anything that makes the 7.40 train less grim" gives a buyer room to surprise you inside a subject you actually care about. Spread the prices too, from a cheap bar of chocolate to the headphones, so your colleague and your parents both find something.

Add things the moment you notice them

The list grows in small moments. You use a friend's Japanese kitchen knife and cannot stop thinking about it. You try a hand cream in a shop. Someone mentions a novel on the radio. Add it there and then, while the wanting is fresh. Ideas caught this way make better gifts than anything you can invent under pressure in December.

Write down the consumables you keep running out of as well. The particular loose-leaf tea, the face serum, the tin of smoked paprika you use in everything. These are dull to give and wonderful to receive. A few newsletters from the brands you like will tell you when something new or seasonal is worth adding, and cost nothing but an unsubscribe in January.

Write it so a stranger could shop from it

Give sizes, colours and model numbers wherever they matter. Then say why you want it. "A beginner's pottery kit, because I want to try throwing this winter" tells a buyer far more than "pottery tools", and it might prompt them to add the apron or a book. The reason turns a line on a list into a gift someone can feel good about choosing.

Every three months, go through the whole thing and cut. Remove what you bought yourself, what you went off, what no longer fits your life. Unwrapping something you bought yourself in June is a small letdown, and it is entirely avoidable.

What you get for starting early

A list built over months turns December from a scramble into something closer to a slow hunt. You have had time to work out what you actually want, so the gifts are better and fewer of them disappoint. Share it with the four or five people who usually buy for you when they ask, and return the favour: keep an eye on their hints through the year in the same way.

Take ten minutes this week to create a Christmas list, give it your five headings, and put the first two things on it. The rest will arrive on its own between now and December.
