This page is dedicated to modeling using paper. With a color printer and few other tools (like scissor and glue) one can create really beautiful and realistic models.
On the right You can find my models that You can download freely. Furthermore the Tutorial page explains how I create my models. It's not a detailed description, but should be enough to start creating Your own models.

An example, that Harry Potter fans will appreciate for sure, is the wizards castle (made by Klaus), almost all built using paper.

Here is a photo of the castle:

You can download the files to build the castle on the site wiltshirecounty.npage.de.
