I would prefer that the store/seller tear my fabrics...recently bought 119 inch wide backing...added 1/3 of a yard for squaring...BIG problem...when I tore it to square, I lost over half a yard...the fabric was folded so crooked, that I lost 9 inches on one side and almost 12 on the other....which meant not enough for the back of my quilt....NOT happy...it's not as bad wne the fabric is 40-44 inches wide...but when you get to wider widths...it can make a huge difference. FYI...I took it back (LQS) and they had enough that they tore what I needed...(they tore the first edge to square it up....and the difference between the selvages was over 9 inches...
