So I bought 2 king size Hobbs 80/20 batting and wanted to preshrink it. I soaked it in the washing machine according to the directions, drained it. I believe it was fine when I put it in the dryer. I fluffed it in the dryer and when it came out a lot of it was shredded. I wonder if any of it is useful--how do I know if the non shredded portions are uniform thickness? How do I know that they also haven't been weakened? Bummer.
