I used to work at the LQS. The biggest thing is a friendly and knowledgable staff. The staff has to know how to do may different techniques and be friendly while explaining it to the customer. Samples help sell kits and fabric but have a variety of samples like a stained glass wall hanging, and throw size quilts in a variety of fabrics and pattern and skill levels. Have some in curves and some simple straight lines. You will have a variety of skill levels for seamstresses. Classes are always good. Offer several in different skill levels from beginner to advanced.
