When ever the voice in my head makes me wonder if I am getting the best answer , I ask the sales person "so what kind of quilting do you do?" since there is so much diversity with in the art/craft they may be expert in something but be very limited in your type/method.
It would be like asking a dedicated hand quilter "so how would you or what would you recommend for machine quilting this?".
The diversity in the art/craft exists in every step of the process.
