I scoured the internet for any document that would allow me to print all 88 Olympic participants' flags in remotely the same size...no dice. So, I created my own so you don't have to endeavor upon the same fruitless quest.
This powerpoint includes the 88 flags that represent countries in the 2014 Winter Olympics. Each flag is on it's own slide. If you'd like to print them, they should be similar in size. I printed them 6 slides to a page so I could have small flags for our Olympic display.
A handful of flags have gray margins above or below - this is only to help you determine where the appropriate edges of partially white flags are.
The name of the corresponding country is listed in the "notes" section in the editing view of PowerPoint. If the font one the first or last slide doesn't show up...don't worry...you're not missing anything.
