Question about shrinking for you techies and scientists
What makes cotton shrink:
a. water
b. Hot water
c. hot air when drying
d. other
I just did a bunch of yardage I got at Goodwill, and I did the loads differently. The firsts one I did I washed it then dried it on hot in the dryer. I usually fold the fabric an extra time lengthwise and serge the cut ends to prevent all that fraying and the thread nests. The ones I dried came out all wonky and are going to have to have the ends either cut off or unsewn, and then the yardage will need to be pressed.
The second load I washed and then hung to dry. I don't think I will be able to tell if they have shrunk more or less than the ones I dried.
Anyone ever done any experimentation on this???
