There is a quilt shop in Jackson, WY. It is called Stitch 'n Time, Inc. It says in the ad in my book that it is "Jackson Hole's Largest fabric, quilting & craft center.
If interested there address is: 955 Alpine Lane, Jackson, WY and their phone # is 888-565-5634 or 307-733-6800.
You may want to call them to find out their store hours. Sometimes that changes after the book comes out.
