Are you looking for crafts to have as decorations/useful things around the house, or as presents?
I have been known to take a couple of Ziploc bags of things like beads, ribbon bits and felt with me on holidays, as I sometimes make little felt stockings as tree decorations and can have fun with decorating those (before you sew the 2 sides together) on hols.
Sewing - I have plans some one of these years to make a table runner and some placemats for our table, with a nice festive design to them. Kind of appliqee (sp?) a poinsettia or holly leaves/berries to a nice background, or something like that.
I occasionally pick up my cross-stitch, I found a few nice festive small patterns a few years back (I didn't save them generally, I printed them and they're safe at home sorry) that are small - maybe 2-3" size - and I am slowly doing a few as other tree decorations. But the actual patterns could be used on larger items - maybe a piece sewn onto a tablemat or teatowel etc? www.jessica-tromp.nl/embroiderycrossstitchfreepatternschristmaschildrencross-stitchgraphs.htm Found 1 website in my links - lots of the older links no longer work sorry.
Both the cross-stitch and felt stockings can also be used as gifts.
Cosy festive beanie hats for the family? And a scarf to make a set? for a knitter.
Another knitting thing, as gifts, is cotton face cloths. They are small enough to be nice holiday projects, but there are a few websites with patterns for the centre - I know I found things like a coffee cup with "Java" written, every letter of the alphabet, a dog, a sun, a flower etc on knitting websites www.thespruce.com/washcloth-knitting-patterns-2115979 might get you started (again my old links are broken - but it was a lot of US websites).
This blog has interesting tutorials for homemade gifts for DCs - a postal play set, felt food, doll's clothes etc - she hasn't posted in a while but I was following her exploits back when I had time to craft (and had my own plans that fell by the wayside).
It's also a great time to do things like early Christmas Cake, summer fruits infusions (in alcohol!), or drying herbs from the garden etc. Or drying flowers for using in arrangements too.
