ooh, we have done LOADS of christmas themed craft, I will need to get some photos. Best so far were some 'mistletoes' for the great-grandparents (by 3 month old DD and 3 yo DS). not sure about making them in to christmas trees, or keeping them unadorned though.
I am not sure how poncetastic mine will be but we're going to have loads if I succeed in my Conquering Christmas Project ! In the meantime, please accept a picture of the gingerbread house that we decorated last year (and did not make from scracth - I've missed the poncetastic point, haven't I?)
