Here's hoping that you've found them by now, but just in case, I have a suggestion: go buy a gift, wrap it, and put it under the tree. If all else fails and they don't show up, you'll be prepared. If the best happens and you find them as you walk in the door, you can return the purchased gift in a day or two. Either way, Christmas is good.
I find that as soon as I remake, replace, rebuild, re-purchase, re-whatever, I find the misplaced items.
