Many artists, especially new ones, ask themselves where can they sell their artwork.
Being accepted into galleries is not an easy task and demands creativity, preserverance, and some connexions, as well as having a name in the market can also have a positive influence.
However if having one's work in a gallery is an objective to follow, there are alternatives that can also be a complement, like selling online.
Nowadays having a website or a blog (or even both) is accessible to most everyone with a computer and it can be a powerful tool to market your art.
But one can also use third party sites to sell the artwork since these are also easy to use and usually don't charge much. Two of the most well known are DeviantArt and Etsy, where one can find original art from many artists, including paintings, sculpture, fabrics, digital art and jewelry.
Other options are ArtFire, ArtByUs, DaWanda, NoBullART and Yessy.
However you must bear in mind that it's not a simple web presence that will sell your work, you will need a good and honest marketing strategy that will transmit confidence to the public, as well as continuously developing your artistic qualities.
