When I was a kid we went to Church every Sunday except Easter, and never attended the Christmas eve service. For Easter we colored eggs and has a massive Easter-egg hunt. On Christmas Eve we made ornaments to be put on the tree. I recall the ornaments were some mixture of flour, water, and salt that we shaped into various things, baked, and painted.
Years later I found the reason we didn't go to Church those days. It seems one of the twice-a-year Christians made a disparaging comment about how my mom dressed her kids on such a special occasion. Being a somewhat stubborn woman, and perhaps a bit passive-aggressive, my mom responded by becoming a 363-day a year Christian. Some of my fondest childhood memories are of those Easter and Christmas eve family events.
Now I go to Easter service and to Christmas Eve service. I wear jeans and nobody says anything. Things have changed I guess.
