I do awesome stockings for my daughters. They’re filled tight w/ small fun things & a few boring things they need to refresh (socks, toothbrush).
Fun things: high quality drawing pencils or hand lettering markers, face masks, soaps and sprays, little stuffed animals, small puzzles or brain teasers, cheap earrings, film for Instax cameras, fake nails, make up, magnets for white board, fuzzy socks, Foil Santa chocolates, candy canes etc.
