I love all the suggestions, but one thing I especially like in stores is a table and chairs, or even a sofa, with a lamp so we can browse through books. One store near us, Three Dudes Quilting, is owned and run by 3 men. They have a mini-kitchen where you can make a cup of tea or coffee, plus they have free HOME-MADE COOKIES every day made by one of the "dudes"!!! How welcoming is that! They have a sofa where we can sit and flip through books and that's really nice. Good luck with your shop!
