We usually start indoors first, but our outside decorations are up by December 1 and I start lighting them that day. No need to wait! There's only 24 days until Christmas!
True. One year I didn't get the outside lights up until a week or two into December. They were hardly up at all before it was time to take them down. Not worth the effort. Now I make sure that they're ready on time.
The holly's up, the house is all bright, The tree is ready, the candles alight; Rejoice and be glad, all children tonight.
