What should I do for my 3D portfolio project?

I'm trying to get into a Graphic Design program and they want to see a portfolio with a lot of variety.. example, I HAVE to have a sketch book even thought I CAN NOT draw.. then theres graphics, photography, etc. I'm creative, but not artsy.. like drawing & sculpting, & I want to do a 3D project for the portfolio, but sculpture I'm thinking is out of the question. What are good project ideas? I was thinking of decorating a chandelier to look really cool... like a newspaper chandelier or buttons or puzzle pieces... i dunno. Any ideas?
