The boys got up to our old tricks of shaking snow off trees onto those below.
Don't - Spend hours holding it up while trying to screw "legs" onto the bottom to stabilize it. You will have sore arms and everyone will be grouchy each time the tree moves slightly.
Don't - Designate more than one person to give directions for straightening the tree - more grouchiness!
Don't - Get such a big tree. (Oh, I'm just kidding about that one)
DO - Put a brace up high on the second level and brace the trunk of the tree right to a wall!! Then all will be well and those "legs" you screwed on to brace the tree will all of a sudden work like a charm.
And now it is up and ready for decorations - our biggest tree ever. Now we just need to make a whole lot of decorations (these, these,and these for starters) since we normally only decorate a 7 foot tree. ;-)
