not sure if this is considered a true custom or not but every Christmas we put up at least 2 Christmas trees, one for the kids & a transformer tree.
the kids tree is done in Disney, Spongebob & Scooby-Doo ornaments so every year I gotta do one for the "Adults" lol
I like decorating our christmas tree with tf's as well. This year I have wfc soundwave with his chest open like he's deploying, with ROTF mail-in ravage and GDO laserbeak with him.
The last several years either Cybertron Thunderblast or Botcon Elita-1 has been our tree's 'angel' topper.
I'd really love to see Hasbro do some sort of advent calender. With all the mini-con molds available I would think they could get away with doing this for around $65.
We have a normal looking tree with traditional Decorations. You have to look around to spot the hidden toys.
Now I'm tempted to try this just to see if anyone else in the house notices. XD Each year our tree has a specific ornament theme and this year's is birds. Perhaps I could get away with throwing a few jets on my tree. Couple Generations figures I have would be great along with Cyberverse Dreadwing and Skyquake.
I put Heroes of Cybertron Starscream, G1 Bumblebee, RTS Legends Optimus on my tree (and other assorted cool stuff) and Botcon 07 Vector Sigma is my topper.
