Although not really the answer for the questions you're asking, I wanted to make a suggestion! In my shop, I sell personalized, hand-painted canvases. They are VERY time-consuming, and definitely not the most enjoyable thing I do, but....I feel that it's really important to have a broad range of items available while getting established (online mainly, locally is already pretty established). When I initially started doing the paintings, my prices were on the rather low end, especially for something that was hand-painted, and took hours to complete. When I decided that I really didn't ENJOY making them like most of the other pieces I have available, I had two options - stop selling them, or raise the price, therefore likely selling less.
The decision to stop selling them would lessen the views of my shop, and make it look like I'm only able to do a small range of products. I want my customers to come to me with custom orders of things they are interested in. Having these pieces in my store, allows them to see that I am not all wreaths and fabric-wrapped canvases. If you REALLY want one of these paintings, I can make them for you, but it's a little more expensive. The thing is, people still want them, but I'm now getting paid more for my time and creativity. It has made it worth it. So, less orders for the things I don't LOVE, but when they are ordered, I make a nice chunk of change! I hope this is helpful! Best of luck with your questions and success! :-)
