My Christmas tree is living, so I've had it "put up" since I bought it two years ago.
This year I strung two strings of solar Christmas lights(blue and warm white) on the tree, and some solar icicle lights(cool white) on the patio wall at the beginning of November, but didn't turn them on until the day after Thanksgiving.
I think I need another string of lights for the tree. I have another string of icicle lights for the other side of the porch, but haven't put them up yet.
Solar Christmas lights are the best invention ever... at least, as long as you have sun in December... lol.
