Hey Messymakesart,
Since you're planning to sell canvases, consider going outside the box - art shows and other local events are great but, can be an expensive investment - fees, tents, licenses, permits, etc. However, the exposure can drive additional sales to your website. Also consider asking friends and family to spread the word as word of mouth is the best advertising and doesn't cost anything. As for the online world, take advantage of Facebook, Twitter, Flicker, Pinterest and Instagram for starters. Then there's Youtube and Vimeo - showing your work through videos can be helpful. Other than your time, using these online services are free.
