Another update on me and my wool dryer balls -- I really do love them for drying yardage. Been doing a lot of prewashing lately and load after load, it's better when it comes out of the dryer with those dryer balls.
Typically I was a couple of pieces of yardage in with my regular color sorted loads and it isn't too bad, but I've had a lot of mostly yardage of various sizes washes. Sure, there is still some tangling to deal with, but much less than it used to be (like 50-75% less). Since I use a range of fabrics of different vintages, it isn't the fabric -- must be the dryer balls!
