They do not have a clue! Most people have never been in a quilt shop and know that good fabric can cost up to $9 a yard, thread is expensive and that does not begin to factor in the many hours of work. Sad but true!
If I do make and sell a quilt for someone I make sure they are aware of this before I start. The other thing is if you live in a small town without a quilt shop you have to travel for your supplies. When Gas got up to $4 a gallon, I had a panic attack!
