When my kids were young I always made them new p.j.'s for Christmas. Now I make them for the grandchildren. In fact I was just cutting them out this evening. I have to make 5 pairs. A friend of mine always bought her grandson new p.j.'s and while they were at Christmas Eve service she would have someone throw into their driveway and tell him Santa had left them. I don't know how our tradition started, probably because when my kids were young I made almost everything they wore.
