I was elected to purchase a sewing machine for my mother and I know absolutely nothing about sewing or sewing machines.
The folks at Creative Sewing took me under their wing and while they could have sold me an expensive piece of junk, they didn't. They showed my wife and I several models in the economy, mid and higher price ranges and then asked specific, detailed questions about what the machine would be used for.
When they found out that it would be primarily for quilting, they took us to the appropriate mid-range machine and gave us a demonstration. They made sure that we could operate it so that we could show my Mom how to!
We walked away with a new machine and a little more knowledge than we went in with!
