Glad you made a purchase to support them.
My favorite LQS is one I just discovered, but it's 140 miles away. Once in a while, as a road trip, I will go. The next closest favorite LQS is 57 miles away. A brand new quilt shop just opened 16 miles away, but she doesn't have much in her shop yet. I did go look and bought a yard of fabric. So yeah, 20 miles for a good shop is nothing. See if you can combine it with other stops in the same area.
