It is difficult to know what will sell for sure. I think art is an expression of you, so you should make art you get excited about and enjoy. Predicting what others will feel when they see your art. If making money is the primary goal you may find you are frustrated doing art that might not inspire you. I make jewelry too, and I look at trends, but make what I enjoy and do it to my best. It is validating when someone purchases it, but the real reward is creating.

Thanks Tom! Your comments are much appreciated!
