Here are the first three…
1. Christmas starts for me on the afternoon or early evening of Christmas Eve when we settle down with a glass of Madiera and a slice of panettone. At that point I know that any advance preparations that haven't been done will now be left undone!
2. One of those advance preparations is the decoration of an old candelabrum with Christmas greenery from the garden. This is my final christmas Eve task before the panettone.
3. Another advance preparation is the poinsettia. My sister always brings this to the family gathering we have the Saturday before Christmas.
