The great thing about cake is it doesn't feel like work. You forget about work. Kids, adults, they all get the same look in their eye when they're decorating cakes... That's the magic right there.
I love decorating my home. I'm a gardener too, so that's usually something I have to play catch up with.
I know that the last thing a book wants is to just sit around unread, serving as an element of interior decorating. So when I have people over, all they have to do is glance at my books, and I implore them to take a few home with them. If I am really ambitious, I pack books into boxes and donate them to prisons.
After student years of flat-sharing and living with other people's taste, I went into decorating overdrive when I acquired my first apartment - its floor plan not much bigger than the vintage Hermes scarves I then wore side-knotted on my head, pirate-style.
My fondest memories are generally the day after Thanksgiving. I get the total decorating Christmas itch.
