into one major? For the past few years I have had an online jewelry business where I make the jewelry, website, and do all the photography. I love all these things but do not know what to major in at school?

I was thinking of graphic design because it's more general than jewelry design (I want to be able to find a job after I get the degree) and was thinking about minoring in Advertising? I'm not too confident in myself though when I think about graphic design. I am more of a hands on artist... Any help would be great, thanks!
