The width of the material is only 45 and when you square up the edges there isn't enough 2 meter + 5in = 83" (39+39+5=83) so I wouldn't even have enough for the length....what I need as I figured it would be: 66w+8(overage on both sides) + 77L+8in(overage on length) = 74x85 which is correct....but a meter is only 39inches at best depending how straight they cut it and this backing is only 45 inches...there just isn't enough for squaring and overage....not to mention when the backing is pieced together I have to remove the salvages and the seam down the middle should be at least 1/2" uggggggg and she is quite upset that she figures because the quilt shop told her that is all she needed was 2 meters + 5 inches...I'm having a hard time convincing her that she doesn't have enough....
