I have enough lead time to make:

a crocheted Nativity set.
My daughter-in-law asked for this in November, I knew there wasn't enough time before Christmas at that point, and sadly I told her so. Then, my daughters saw it and wanted it, too! Well, it is too cute for words, and I want a set, too!

I like that the pieces are small and can (mostly) be made with left over yarn. I did buy some special colors. I didn't think my yarn colors would be bright enough for the Magi. I haven't found grey for the donkey, either. Who knows? I haven't dug all the way to the bottom of my left over yarn bags!
One other change: I use B B's for weights. I make the little bags as she said, but I use B B's to fill them. I'm not sure I'll make the star to be free-standing, either. I may fasten the dowel to the back of the stable.....
I have to get more of the set made before I decide.
Four Nativity sets added to my list of works in progress.......
