Over the years of running an Etsy shop, I've noticed something strange. If I love something, it's appreciated but it doesn't sell, at least not easily. Conversely, if I'm "neutral" about something, it sells easily. [The rest fall somewhere inbetween.] A psychologist might say that it's because I'm "holding on to it emotionally", but this isn't true because I don't get attached to my work that way; I'm too busy looking at my next project.
I love making little collages like this one, just listed today. I've had a similar one in the shop that has been "favorited" 56 times. I renewed the listing, and it continues to be popular. But no sale. [No, it's not the price.] When I first made it, I really, really loved it... you see where I'm going with this.
I just thought it was an interesting observation. All in a day's work!
