If you own and run a business on the internet, how would you list that in your resume? -

I m going to be starting my own business in a few weeks, selling various handmade items such as: jewelry, sculpture, pottery, journals, sketchbooks, screen printed items [T-shirts, napkins, tablecloths], scarfs, posters, prints, etc. that I ve made. In addition to making all of the items, I ve also been working on a marketing campaign for my online store as well, including newspaper ads, [both for print and online] and video ads. What is the correct way to list something like that on a resume? [Last semester, the profs taught us how to write our resumes since it was an important part of our portfolios, but they never covered what you should do if you run a business on the internet. I m just asking since I would like to keep my resume up to date.]

simply explain what you did.
