I've knitted Xmas crackers and baubles for the tree, also a miniature Santa's washing line, which has vest, pants socks jacket and trousers with braces all held onto a "washing line" with miniature pegs. I havnt realy decorated this year, so non of this is up or I'd take a photo and show it.
I started to knit a snowman earlier this year, but never felt excited enough to finish it.
My friend has a knitted nativity which she has out every year.
