Wow, you're really going all out! I love making my own things too. I'm currently working on an altar cloth but not sure I'll get it finished before then. I do a major cleaning of the house from top to bottom and that's taking a lot of my time right now. I purge all the junk that has accumulated throughout the year too.
I often make a Spanish turkey soup for dinner with an orange salad and fresh bread or rolls. We also candy orange peels and make crystalized ginger.
Will you have guests, or are you solitary?
Well, the nice thing about the tablecloths is that it's just one piece with a hem around the edge. And I'm lucky enough to have an almost-mother-in-law who buys me at least one very expensive item a year for the holidays and a few years back it was a heavy duty Singer sewing machine. I hope your altar cloth gets done! That sounds really nice!
We always make Yule about quiet prayers in the morning (over the log) and a big party in the evening so we're going to be having some 20-25 people over in a small house. Yule is kind of my big middle finger to all the conventional obligations of the holiday season even though they have a lot in common. It means I get to spend my holiday season with the people I love and care about and give all of my holiday labor to them instead of people I'm obligated to interact with. (I don't have such a great biological family.) I take it from your desire for simple you're gonna have a more solitary or immediate household only sort of Yule?
How funny, we're actually working on the top to bottom cleaning of the house too right now, and getting rid of a lot of old stuff we don't need also! I need to reach out to my local Purple Heart chapters and throw some boxes of donation items their way. It's fairly clean around the house right now because we unexpectedly hosted my aforementioned MIL for Thanksgiving this year, but we still have things to purge. Decorating starts on the 1st when we set up the tree.
That soup sounds nice. I know we're doing a potato and leek soup this year... I have leeks out in my garden, silently existing under the light blanket of snow, still surprisingly alive! They did rather well for my first time growing them and I like to cook as much from my garden for Yule each year as I can so we thought it would be nice and hearty and a good use of a vegetable that's not common for us.

We're also using some of the winter squashes from the garden this year (crown pumpkin and honey-nut butternut), but I'm not sure where yet. Usually I'd halve and stuff them with mushrooms and rice but these ones got very beat up so I'd rather chop them up and use them that way.
I broke my sewing machine needle trying to hem it when I hit a pin. First needle broken in years. Had to go get a new one. Maybe I'll try sewing again today or tomorrow.
