when you buy fabric, do you expect any extra length?
I know I am upset if I am shorted an 1/8 inch on a cut, and pleased to get extra.
When a piece is rotary cut, do ou expect to get the piece " cut to the neaarest thread" - or do you want/ expect " a litle extra"?
I am not aware of any other commodiity - such as meat , gold, gasoline - where we think we are entitled to " exrea"
