Just after the birth of our third child I decided our family needed a special "skirt" for our Christmas tree.  My obsession with hand prints and family traditions came together, with some help from a friend, to create this:

We doubled some plain white fabric and edged it with red and green Christmas prints.  (I'm so thankful for Carol's serger!)  That year and every year since each child has put his or her handprint on the tree skirt. (Well, actually, the first year dd10 was a baby and uncooperative with her hands, so we had to put her footprints on it.)  After it dries I label the name, year, and age.  Because the skirt is beginning to fill I regretfully had to place a limit on the handprints, so it was decided this was ds17's last year to place his hands on the skirt.  (He's hand's finished growing anyway.  Sniff. Sniff.)  He's entering manhood and thinks he's too old for it.  I tell him to give me grandchildren (One day!) and I will make a new skirt and put up two trees!

Another yearly tradition is to place each child's picture on the tree in a handmade ornament.  (One day I'll need a tree for just those!) DS17 may have to continue bearing with that one each year.
