I agree to all of the above and:
1) Make sure the staff know how to sew!!!!! Know how to make quilts!!!!!
2) Make sure the staff are as nice to men as they are women that walk in the store.....they buy too!!!
3) I go to one shop that I dread going to (it's so close!!!). They have a staff person that follows me around, always making suggestions (even when I don't ask) and will try to drag me from one end to the other of the store. She exhausts me!!! Always grabs books and says "you should buy this", etc, etc, etc. She's on overload....I hate it!
good luck!
