Do an experiment. Take a yard of printed cotton. Measure both the length and width. Machine wash & dry. I have found that if you put a yard in, you get a yard out BUT it almost always shrinks width of fabric. Sometimes a half inch, sometimes almost 2. I prewash everything. Prints shrink and Batiks bleed. I am also a starcher. 1/2 StaFlo, 1/2 water, dip the fabric, dry till damp, then iron.
