If you were into Mr. Potato Head as a kid, then you'll love the Xoddo site where you can design, build and order your very own custom plush. Fusing the designer toy craze with the trend for mass customization, Xoddo follows the business model of other online sites that allow users to create unique one off items. A plush will cost you $28 while a smaller beanie version runs $18.

It would be great if they offered the ability to upload your own pattern for more advanced users.

Mass customization has been around for a while now ... and although it hasn't quite taken off, it is great to see all these services and tools popping up that allow for experimentation and creativity.
