Many artists have struggled with this question, myself included. I have created many smaller sized paintings in the past. These generally sell much faster than my larger scaled artworks, mainly because they are cheaper, easier to hang, easier to transport, etc.
But, my tendency is to work BIG! I love the freedom of movement that a large canvas brings, but because of my process and attention to detail, they take a long time to produce. Thus, I have to charge seemingly outrageous prices, making these paintings more difficult to sell.
What do you think of creating small scale artworks to sell more?
I am interested in hearing your thoughts and experience.
