I was looking at a few doll photos lately and saw some people who kept things inside the body of their doll like the COA card, and that got me to thinking. Since dolls are hollow, there's definitely space inside for extras. Do people tend to put things in their dolls? For instance, I have a Build-A-Bear and when making her they put a "heart" inside made of fabric. I was wondering if anybody else has ever put a "heart" or a "mind" inside their doll's body or head? I was thinking it would be very cute to use something like a small real gemstone but that would probably rattle around and damage the body unless it was padded or wrapped with something. I was also thinking of perhaps a small glass marble or maybe even a bead that could be strung onto the elastic so it wouldn't rattle. Though I would want to make sure it did not restrict the elastic's movements either. I hadn't seen anybody discussing this but I thought it was a cute idea, and if anybody's tried it, I'd love to hear about it.
