This is seriously cool I wish I could buy one but I'm positive they will go for a small fortune. here is what the creator said about how they made them.. and you should leave some comments for them at craftster on this thread
"They are made from fibreglass. They are quite light, they have a stem at the back of the neck that leads down to the waist where there is a back brace so all the weight is on their hips. As for the eyes, they are made from vac form plastic, which is a heatable plastic you can suck around a form to make a shape. We made a solid semi sphere buck by pouring plaster into half a big plastic bubble. I think the bubbles are normally used for xmas decorations, to fill with lollies and stuff. I used the vac form machine at school, thank goodness we had that available, otherwise we would have had to pay a company to do it for us at who knows what cost. The coloured part of the eye is this stuff called mylar, which was scraps left over from a show at school. It's like this mirror paper that you can stretch and staple to things to make your own mirrors. We coloured it with glass paints you can get from an art store. The eyelashes are just fake nylon hair, we used a curling rod to shape them.
There is a mechanism (crude as it may be) inside the eye which we developed so the eyelashes can flutter as the models walk. It was a difficult thing to get right, but we got there in the end"
You can also watch a video of the fashion show below, it takes a little while to get to the real blythe dolls but it is very cool to see them in action. This is one of the coolest things I have ever seen.
