Note: 1. In all cases the fabric should be unfolded and then treated for shrinkage. 2. Care should be taken that the bucket or the vessel used is not rusty. 11.4 STRAIGHTENING OF FABRIC: a. First Method: Many times fabric needs to be straightened before the garment is cut out. Draw out a crosswise thread and cut fabric along the thread if the fabric has not been torn from the roll. Then the garment will fit better and hold its shape longer. To see whether it is straight, place it on a large table and make a lengthwise fold down the center to meet both selvedge together smooth out wrinkles. If the two selvedges meet evenly with the side of the table and the raw edges come together even with the ends of the table, then the fabric is straight.
