How do I store my DD?

I'm moving and I have to box her up.

I'd say disassemble your DD at the waist, if you don't still have the original box. I've shipped a few this way, you can use a much smaller box. It can be hard to find a box that's both narrow and around 2' long. Probably not a bad idea to pack all your DD clothes, wigs, etc. in the same box, if possible, just make sure to put everything in bags, and especially wrap up the head on it's own.
