Lulu has improved their calendar binding rings this year. Last year calendars had a spiral binding ring, while this year's binding ring is more straight. It makes things a lot better as the ends don't get stuck in the wrong places etc, like the spiral binding does.

One thing I didn't like was that the holes for hanging the calendar seemed to stick together a little bit. It's like the punch pressed so hard that the pages stuck together around the hole. It wasn't too much of a problem to gently pull them apart, although a slight ring around the hole gets torn from the picture.
