It happens...it happened at our quilt shop...not just fabric, but other items too...even quilt samples....we ended up nailing things to the walls...attaching jingle bells...still even had some taken after that...no shame. Also at a quilt show, many vendors had items stolen. She got caught...and we did find out who she was...and when she did come to our shop...we followed her just a few steps behind. We had others we were suspicious of and also followed them. I find it hard to believe that quilters can steal, but we found out otherwise. Sad that people do. Hope this person gets caught.
