I swear I don't remember this kind of mess when I washed fabric a couple of years ago. Granted, I wasn't washing eleven different pieces back then, and I was using my washing machine that doesn't have an agitator. I washed it on the gentle cycle.
After thirty minutes of untangling and trimming, I was left with this:
Did I miss something? Is there something you can do to prevent this? Or is this perfectly normal?
