Food is a fall back of mine, as anything for the kitchen goes down well. This Milk Chocolate Stirrer would be a perfect stocking filler, however these Charbonnel et Walker Pink Champagne Truffles always steal the show. As well as food, a cute mug is a good present too, this Patone Mug and this Urban Outfitters Elephant Tea Mug offering are two of my top picks.
A new book or stationery will always go down a treat with those who are hard to buy for. This Ohh Deer Notepad set or Copper Marble A4 Pad would be great for anybody at school, work or who just likes dreamy looking stationery. As for books, it's hard to know somebody's tastes, but if you've got a slight inkling then I would recommend non-fiction books. If they're into beauty, Pretty Honest is a good book to buy, whilst The Little Book of Hygge is good for homebodies and The Tattoo Dictionary is good for any tattoo lovers. There's a book for every hobby, so I'm sure that this would be a great place to start.
If you are really stuck, then technology is a good starter point too and I would recommend a novelty lens for your phone if you're on a budget or a polaroid camera if your price point is a little higher. Another one that would go down a treat if you have a little bit more money to spend on someone would be a Crosley Record Player, especially if you know they've got a bare space to put it in and are in to their music.
Here are some of my top picks to jog your mind and give you a few ideas:
