Wow, that storage and organization looks awesome. Hell, I would have flown myself out to help you move for free just to be exposed to such poster awesomeness.
The ET party sounds awesome. I tried to do something similar for my daughter's Finding Nemo / Dory themed 3rd birthday party. Bought some Finding Dory banners (pics soon), but they didn't arrive in time. Bought a Finding Dory 6- or 8-sheet (pics soon), but there wasn't anywhere to put it on the wall at the restaurant where we had the party. Alas, had to settle for Party City decorations.
