I put my Mario ornament up that I printed off from one of Luigison's threads last year!
What I usually do is in this order
-Put on the top ornament
-put on the lights
-put on the bought ornaments
-put on the homemade ornaments (The glued bean reef from kindergarten XD)
-last but not least light everything up!
Oh yeah, my family used to use a fake tree, like ever since I was 2, but then we started getting real ones when I was 13.
