I used the paper from our weekend magazine, it's a bit better quality than newspaper so the newsprint doesn't smudge once glued. To make the circles, I used a shot glass as a template (it doesn't see any other use nowadays, sadly).
Then I blew up a water balloon and started glueing the circles onto it, overlapping them and working my way around until the whole balloon was covered.
The font size and style worked really well. Yes, some panels are upside down, and no, it wasn't intentional.
Then I decided to make more colourful ones. Here is one in tonal greens using paper from the same magazine:
And in what could be a world first, I made some chevron ornaments. You saw them here first people. These were paper bags that I had left over from Sienna's birthday party. They looked better in my head.
Time taken: 30 minutes to make one
Result: Our Christmas tree looks very, um, rustic??! Ok, it totally looks like we can't afford Christmas decorations, but I kinda like it, as do the girls. My job here is done.
