Hi I wanted to inform those who could be interested that my new diagram " Pentagonal Coaster and Tato" is now for sale at The Source. It contains the diagram for a pentagonal coaster, its variaciĆ³n and a Tato, all from the same base, so it's 3 models for the price of one. You don't have to be an OUSA member to buy from the Source.
The direct link to purchase the diagram is https://origamiusa.org/catalog/products/pentagonal-coaster-and-tato-pdf there you can see a picture of the folded coaster, a picture of the Tato can be seen at http://www.flickr.com/photos/georigami/31457657931/ If you like what you see there you can check the rest of the The Source download catalog for my other diagrams, just use Jaramillo as the search criteria at https://origamiusa.org/catalog/newest-downloads -- Jorge Jaramillo
