At some point during this hundred-days process, I attempted to do this. We bought the hooks, I got the drill all charged ... and found out that the hooks wouldn't fit across the back of the door. I've looked and looked, and haven't been able to find any sets of smaller hooks. Plus I couldn't really remember why I wanted them there anyway. Maybe for hanging J-cub's coats up.
We'll see, anyway. I'll keep on looking for those elusive hooks.
