My background is in mechanical engineering, but in my spare time I build furniture & sculpture out of concrete, metal, & wood. My methods to design so far have been to make up dimensions & hope for the best. Some pieces I'm been proud of... others are a mess of disproportionate components. So I'm looking to learn some design principles (ideally applied to furniture & interior architecture) while living in a European city for a few weeks / months. Sort of an 'educational vacation'. I searched the "schools" forum but couldn't find what I was looking for. Anyone have any tips?
