Yep, frozen solid.
It's not very smooth. It was windy. There were also a lot of little 'things' in the water... like the fuzzes off of dandelions. They were surely some kind of bits from weeds having gone to seed. Seeing them in the air on Friday made me think they might've been those other 'white' things. Actually, I did see a bunch of white things coming down in the middle of the afternoon. I wasn't sure if they were really the 's' things or not... until they landed on the deck and melted away. At least they were short-lived. I'm sure there'll be more soon enough. Ehn.
It's good sewing weather, though. I'm making progress! :)
