I was going to do this epic post-it series before my last day at work and give the whole grand mosaic of memories as a parting gift to my friend, to say thank you for sharing the moments with me. But the further I got into this, the more exhausted I became and the more worried about taxing the friendship, so maybe it's time to just keep what I have and give this project a rest.
Never underestimate the versatility of white-out; it's not just for mistakes anymore!
Update: I gave these to him in person. They were well received :)
