Copy of a magazine like Private Eye/PC Gamer/ Cycling (obviously adjust to taste!) as it looks cute rolled up sticking out of the stocking and takes up some room
Lovely wool socks from Falke/ Injinji
Handkerchief/pocket squares-I’ve had some lovely ones from Etsy, Folksy and also from local craft fairs over the years- tbh I think if you’re crafty they must be easy enough to make and use fabric meaningful for the recipient.
Fancy hot chocolate-Green and Blacks is great and maybe a mug or travel mug
Little Moleskine or Leuchturm notebook
Little game like Dobble
Depends on the size of your stocking but that tends to be more than enough for DH, DF, DFIL.
I found a bear care set at a ridiculous price in a sale. It has beard shampoo, beard oil, scissors and a comb. I'm wrapping each item individually for the stocking. I might see if I can find a smallish wash bag to go with it. Otherwise, chocolate, face cream, any small, hobby related items, One year I made an iou notebook for dh - just bought a small notebook and on each page wrote something like 'Chinese takeaway', 'DVD rental of dh choice', 'one week of me taking out the rubbish ', (normally dh job). I managed to come up with enough ideas that dh could claim one a week for almost the whole year. Most didn't involve money and apart from a meal out or takeaway, those that did were still inexpensive.
