How can I build a low cost greenhouse over a 4'x8' raised garden bed?

I would like to winter over some of my potted plants that were placed throughout my landscape during the summer but have limited options and space. I am thinking about doing a sort of greenhouse type cover over an existing 4'x8' vegetable garden bed that is not in use during the winter months and would like some ideas.
