I have found that the shortage usually comes when I buy from Joanne's and the fabric is 90 or 108 inches wide - they try to cut it instead of tearing on the grain because the fabric that wide usually isn't folded straight and cutting seems to leave less that a yard you've asked for.. I buy my fabric at a small store in Homer and the clerks there usually add a small amount to the total yardage I ask for... The fabric is a little more expensive but I get what I ask for..plus more. They are pleasant and more than helpful. I live in a small town and next town with fabric is 75 - 80 miles away...
