I used to make little paper finger-puppet mice in school all the time, I wouldn't sit in lessons but instead kept creeping to the corner and stealing art supplies to make these little guys - during that time I also had a thing for collecting chalk dust and eating the ribbons on my dresses, so I think teachers preferred me doing something constructive and vaguely normal by comparison.
I then went through a phase of making many many pom-poms. My mother then made the mistake of showing me how to make woolen dolls, like this - http://www.momsandkids.co.uk/images/wooldoll8.jpg - mine were normally thinner, all different colours, some taller, some smaller baby dolls, some with longer hair, coloured with felt-tip pens, etc. every one of them had a family and genealogy. As a kid I had the whole empty dinning room to myself so I made enough to cover my dining room floor, at that point I'd put them away and start again.
Then I started making these - http://littleredbook.weebly.com/uploads/3/9/8/1/3981459/5856916.jpg?375 - creatures of my own creation made from plasterscene, they were ponies with extra long manes, piggy tails, and with two flippers as front legs and one conjoined flipper at the back, they also wore hats that were turned up at the front (like the ones worn by Blossom and Six in the TV show Blossom - also an obsession of mine, along with Mork and Mindy). *shrugs* These, like the woolen dolls, were infinite in their variation and had family and genealogy, and were made on mass with my becoming hyper-focused so I refused to do ANYTHING else.
There are probably more examples like this from my childhood, it's talking about strange stuff like this and remembering what I was like as a kid that makes me wonder why the hell this whole aspie thing wasn't caught sooner, I was far from a normal child.
