The "just married woman" 's method.
Going through the doorstep of her new house. It's ancestral, a bit macho but so effective ! It's possible to shower her with kisses during the move, hopefully both our hands are busy !

Bend the legs enough to obtain a minimum length when going through the doors. In my case i prefer to arrange her arms crossed on her stomach (be very careful with the fingers which could poke if the hands don't slip on the clothes)

Disadvandage :
- keep an eye at the tops (head and feet) and at the hands too when moving.
- support the weight of the doll but don't grip her with your fingers !
- This is ok for a flat way but be careful when climbing a stair (especially if it turns)
- be careful with your buckle's belt or your watch (take them away).

A chair with wheels : economical, not much tiredness, but be careful with the different levels of the floors or the carpet. Avoid the armrests, more cumbersome than useful in my opinion. To put the doll on the chair or to lift her up, choose a chair's model with a brake or use a wedge (it's not easy to lift up a doll from a chair !) ; once lifted up, use the "just married woman" 's method above.

A wheelchair : used by a famous Realdoll (Bianca from Lars & the real girls), this means of transport is perfect for the outings. The fact that the feet lean on something should free the bottom ot the thighs of their own weight and this is a must !

The stand with wheels : this stand is an ingenious homemade assembly, made with heating pipes. Basically, it allows the doll to stand up for a photoshoot but if you add 4 wheels under the piece of plywood then you obtain an easy way to move your doll through your house.

Disadvantage :
- the balance, the spin, the jamming of the wheels (doorstep, carpet, dog's tail...)

If your are not a handyman, you can buy one on the Internet (but without the wheels)
