My version of a "Can't Miss" shop when I'm traveling would have to include:
a promotional shelf - older line fabrics for cheaper prices
kits to match display quilts
helpful, but not intrusive workers
something unique that sets the shop apart
For my local shop I also want classes, a shopper loyalty card, people who are enthusiastic about the "Show and tells" I bring in.
I'm thinking what we want in a shop to visit would depend on what we have at home, level of expertise ...
