I have modeled three models of rabbit, spider and goose dolls for you and have included their tutorial video for you.
The videos are time-lapse and although they do not have subtitles, the process in them is very clear and repeatable.
If you are interested in modeling fabric objects other than clothes in Clo3d, this tutorial can be of great help to you and you can purchase a license with a tutorial, and otherwise, if you only need doll models, you can purchase a license that only includes models.
