I have been told by the manager of Joanns that people have been stealing the 45mm rotary blades out of the packages of 5! I had asked him why there were never any on the rack any more? He said you have to get them from a manager, who keeps them locked up, because of it. I know they're expensive but.......is nothing sacred anymore???? It's sad that sewers ( and quilters) have to steal things?
