This year I used white-oak nuts to make my acorn flour. I could tell from the first day that I started soaking it that it was going to be different from the red-oak acorn flour I made last year. Here are the ground-up nut meats when I first set them to soak, this year:

(Here, for comparison, are what last year's nuts looked like when I first set them to soak)

Hmm, actually, in photos they look pretty similar. Take it from me: this year's batch had a yellower cast, and last year's had a red-browner cast.
Just today I've dried the ground-up nuts after lots of soaking and changes of water. I'll let you know when I've baked this year's cake.
And the leaf wreath: I've wanted to do this for years, and sometime before Halloween, I finally did it:
Collected bright orange-red leaves:

Sorted them into groups of three (this was fun: getting the perfect threesomes together):

Joined them together (with Jiji's help):

Formed them into a circle:

And hung the circle on the door:

It lasted like that for, oh... 24 hours maybe? Then it started to wither. Here it is some days later:

And now it looks *really* sad. I'll probably take it down soon and put up something else--a circle of old man's beard, maybe. But it was very fun to make, and very satisfying to see it on the door.
