So after collecting enough, I got a bunch of them printed at Costco (I spent about $10 for like 15 prints). Then I went to Ikea to get frames, spending around $40. So this was basically a $50 thing.
And then a few nights ago I hung them. I didn't even bother laying everything out on the floor to see the arrangement, I simply hung them one by one on the whim.
Here's what our office wall used to look like. Yup, except for the window and memo board, there was nothing going on.
