Carry bag

Whatever you feel most comfortable with! The carry bag I use for MSDs is kind of big & not very padded, so I use their box pillows to add extra protection. On the other hand, my carry cases for my mature tinies are hard shells that have straps to hold the dolls in place, so I don't bother with anything extra.

 

I like to use the pillows or a blanket, mostly to give the more frail parts like hands or fantasy parts, more cushion, and also keep resin from being scratched by the zipper.

 

I carry mine about in my workaday backpack with just a face-covering to protect the faceup. It's really down to what you feel comfortable doing with your dolls.

If they are smaller dolls or I'm taking several, I'll put them in a cushioned bag to keep them together and from getting jumbled up among the other bits and pieces in my backpack.

When it comes to my Pocket Fairy (1/8) she didn't come with any sort of padding at all, just a paperboard box with elastics. So when I take her out, either to size props/fabrics or just to play, I wrap her in a microfibre towel and secure her in a pouch that's just big enough to hold the swaddle - it's basically a small toiletry/cosmetics bag, but it works for her size. Then I feel safe putting her in my bag.

If you feel a little unsure, always err on the side of caution. It's better to be overcautious than underprepared. If you'd feel more secure knowing she's in her pillow bag, definitely use it. You could always do a test run inside your house with just the doll in the carry bag - walk around for five or so minutes, see if she wiggles around a lot or if the bag feels flimsy when a small amount of pressure is applied to it (say leaning against a wall or standing in a line with someone who stands a bit too close). If it does, you definitely want the extra padding.
