My 100 cards are done.
When we lived in Germany, we went all out - inside only - lights on the outside aren't really done there. Christmas began early like 11/11, St Martin's day with a lantern procession through the town, sugared prezels, and the raffling off of the Christmas goose. Every neighbor had an advent wreath.
On December 6, St. Nichlaus came - with his staff (he was a bishop, you know) and his sidekick, Black Peter, rattling chains. He read your transgressions from a BIG book - the little kids were good as gold while he was there. Then he'd give them some sweets and go. A short time later, the bell would ring and there would be a sack of presents.
There was always a Christkindlmarkt in the larger towns - the smell of chestnuts roasting over charcoal always takes me back, although I can't stand the taste of them. But there was always burnt sugar nuts, and gluhwein too, and gingerbread cookies and stalls full of beautiful blown glass and carved wooden ornaments.
We always had a real tree, that took us a week to decorate. I baked the whole month of December - usually about 100 dozen cookies. Bouquets of flowers. Stockings for all. We'd have 20 -30 single GI's for dinner - leave your rank at the door - I can't imagine being able to afford to feed that many now, let alone prepare stockings for them.
We have an artificial tree now, slim, an hour does it - then I'm out of steam and stop. We have a giant artificial wreath for the front of the house - dh puts it out with a flood light on it. We'll probably put it all up Thanksgiving weekend, because we're home this year.
The year I graduated from College, in December, I planned a trip to WDW with my neighbor - and left DH to do Christmas. He put out the things that were important to HIM. After that we simplified A LOT because I realized lots of stuff I was doing because I thought he expected it - and the reality was - it didn't matter to him.
Buffy, if it was me, i'd instigate a discussion with the kids about what they thought was special about the holiday and what decor THEY love. Let each one pick one favorite and do that and call it done. Going "all out" may be stressing yourself needlessly.
