Some great ideas. Here are mine.
I would like to see quilts displayed on the walls, lots of them : )
I think that anyone selling machines should be able to answer questions about all the machines. Makes me nervous when they say well I don't know. The lady I bought my machine from was like that. Although I really liked her, and she was really great in the CS dept she lacked the knowledge I was looking for on my machine. The sales rep should know the difference between machines as well. I realize all of this would be difficult, but sales reps should not just have knowledge about the machines they cater to, but all that they carry. They seem to favor brands.
