Hi! This is a great question. I don't have an answer, except that I certainly hope not!! Every single item in my shop is made to order.
I find it works great for me as a seller because each thing is made especially for the person ordering it, to her specifications. They can be completely customized and personalized with the style, size, color, etc that a person chooses, and she can know that it was made with care, just for her, to be the only one like it in the world. Of course a lot of customers just want it to look exactly the way it does in the photos, and that's fine, too.
But I also find it's great because it cuts down on the amount of inventory I have. I wanted to create a business that was fully portable and travel friendly, and I have! :)
I know this doesn't really answer your question, from a customers perspective, but I can tell you that I have yet to hear from someone for whom this method has been a turn-off.
