Every year someone on your list says they don't want anything. They're usually lying — they just don't want bad things. Here's what we'd pick.
Under £30
The enamel mug. Nothing about it screams gift, which is exactly why it works as one. A mug that looks good on a shelf for ten years is a better present than a scented candle they'll burn in three.
Under £75
Pair the logo tee with the starter bundle — it lands as a thoughtful set rather than one obvious thing.
Under £150
The quarterly subscription. It spreads the gift across four seasons; you get to be the 'something nice showed up today' friend three more times.
The secret to gifting people who don't do gifts is to give them permission to keep the thing around without feeling guilty about it. Quietly excellent objects — mugs, tees, well-designed software — pass that test.
