I found these tips somewhat useful. I do the battery and twist tie thing. As for the wrapping paper, the idea of 8 kinds of wrapping paper boggles the mind.
I am a huge believer in making Christmas easy, though I'm convinced some people like rushing, stressing and feeding obnoxious relatives. Our Christmas goes something like this:
1) Be awakened at an unmentionable hour.
2) Let kids indulge in a free for all.
3) Console child whose gift was opened by a sibling.
4) Since the coffee is done by now, begin drinking mimosas and let the kids have stocking candy for breakfast.
5) Continue above until a late lunch, consisting of foods my children will actually eat. This year our extremely non-Martha menu includes:
turkey roll-pressed, processed meat being a favorite of my children over actual turkey
cookies, cookies, cookies
sprite -in a wine glass, they love a wine glass
6) Pray the rest of the day sees no more toy breakage
7) Sit bleary eyed, sipping a bourbon, wonder where the day went and quite unoriginally say a prayer of thanks that this particular family is mine. What more could I really want?
Merry Christmas from our family to yours
