Years ago, I used to do some craft shows and consignment stalls. I couldn't believe how many people would come by snap, a picture and say they were sure they could make it themselves at home...I actually heard them saying that....tsk tsk......I think in a quilt shop, I would first ask the salesperson if she/he would mind and explain why I was doing it......If that person says no, then I probably wouldn't go back but I would respect the answer.....There really are too many dishonest people out there.
