Hi, I'm a novice user hoping for some tips on efficiently starting up a 2' x 4' project. I'll want to eventually print at 300 dpi; I'll also want to be able to print a much smaller version -- say on 11" x 17" paper. I'm new to vector drawing and not sure where to begin. Should I specify a paper size initially or just get the proportions right and set size upon printing?

Any advice on crucial first steps would be appreciated!

Thanks,
Dave
