What has worked for me is a new line of art that has generated more pieces sold than I ever expected. Since it's a new style and fast, price is the main factor that seems to be working. At one point my framed 1/2 sheet watercolors (20x28 inch frame) sold for $750.00. It's been years since one has sold. When demand for an artists work increases the price, it's not a wise thing to lower the price when there is an economic downturn. In the Maritime Provinces of Canada, art for the average artist has dropped drastically. It's either modest price or high end art that seems to be moving. The below answers are great, and I'm using most of the suggestions, but my new works are colorful, different and more than affordable. Most sales are generated by word of mouth and social media. My website is a presence, but doesn't bring sales like I had hoped. So, maybe exciting work by new artists that is affordable for the average family will work for you. It has for me with over 270 paintings sold since July 12 of 2016 when my first Plyatism painting sold. Check out Plyatism on Google or visit ivanfraser.ca. Hope this helps. Ivan
