i do understand, i did work for joanns at one time, but let me tell you, most people that work there now DO NOT sew..so they have no clue as to how much a yard is, or 3/4 even, it is a sad state when you have to watch everyone like a hawk, but if you have to, you have to. I would definately call the manager and let them know, this isnt the first time you have been cheated..i wish you luck,
