Since owning a house my partner and I have really embraced Fall/Thanksgiving/Halloween decor from mid-September until early November (we're in Canada where Thanksgiving is in October). I like fancy/pretty shit so we have a bunch of blown glass and porcelain stuff, candles, some skull/haunted-like figurines, wreaths and vases with faux flowers/black branches. The last two Thanksgivings my partner bought me a bouquet of orange/yellow flowers for the dining table too.
I bake at least once for Thanksgiving and once for Halloween. We also watch Halloween Baking Championship every year, and try to squeeze in some horror flicks too.
We also listen to a very wide variety of fall/Halloween music throughout the season. This year we particularly enjoyed the Nemos dreamscapes compilations (example).
Last two skills I've successfully learned:
Giving subcutaneous fluids to my cat. Followed vet instructions and watched several how-to videos online for different tempered cats.
Making macarons. Followed online recipes, tried some different techniques and troubleshooting through trial and error.
More recently, I have been trying to teach myself HTML whenever I have pockets of free time during the work day. I'm following the mozilla.org Intro to HTML as a guide.
