Stiles gets his stocking from Wonderland, because Derek grabbed it for him while his future-self was here. He's tucked a huge Gaeilge to English dictionary in it, as a half-joke half-sincere present.

He also gets what was in Derek's stocking: Papa Hale's jacket that he wore back home. If Stiles asks about it he'll pretend it's not a big deal but it kind of is because it's the last thing he has of his dad's.
