Neck Mod (Lengthening)

I would search the term “neck doughnut” for what you’re looking for—and I would advise you to try out the search feature on DoA—a lot of the things you’re creating threads for have been discussed in other places, like pictures of Dollmore trinities and lusions—you can find a lot of what you’re looking for on here!!

To lengthen a neck without permanently altering the resin, all you’d want to do is either get a neck doughnut, which is a little piece of resin that would put more space between the top of the neck and the head’s socket, or put in a kip (which is a flexible silicone disc that increases friction to improve joint movement!) or hot glue suede the crap out of the socket on the head, to make it so that the neck doesn’t go in as deeply. I lengthen most necks by hot glue sueding, because it requires no specialized equipment, and you can choose how thick it is, and it just scrapes off once you decide you’d like the head on a different body, or you’d like more or less cushion there.

if you’re looking for a significant amount of length (like more length than the head-hope is deep) you’d have to do an additive mod on the top of the neck joint, where you’d put apoxie or milliput on the top of the neck, and then let it cure and match it to have a longer neck. You could also sculpt a bigger, taller neck doughnut that is removable, if you put some Saran Wrap in between the neck and the apoxie, but it would probably look somewhat like the extra neck joints in Doll Chateau dolls look, and would give a bit of an inhuman vibe to the doll you’re modding.
