I found the one quilting shop in Jackson Hole where we were based and made some modest purchases. My main observation was that the prices have risen somewhat since I last bought material in the US. That said, they as still cheaper than I could buy them in the UK. Here are some of the fabrics ($12 p y) I bought because I liked them.
Here are a couple of blues that I bought because I needed them for my Lady of the Lake quilt.
