I like:
food bits - fruit curds, chocolate, sweets, candied orange slices, sugar cubes (what can I say, I love sugar cubes), posh hot chocolate
toiletries - nice shower gel, bath salts or oil, soap, travel size of my perfume, shower bombs, flannels, lip balm (I love lip balm), mascara, hair bands
socks but not fluffy ones, just normal ones, pants
stuff - we don't do novelty tat because I don't like the waste, but seeds, books, charging cables, matches in cool looking boxes, enamel pin badges, boot laces, kitchenware such as an egg cup, or a spork, scratch cards, pen
This year I put some photo booth style strips of photos that had been printed onto magnetic backing in OH's stocking and they went down really well
