We finally gave the old tennis/dryer ball as fabric softener trick a go. And, we're happy to report, it worked!We used 3 tennis balls and two blue dryer balls (at the recommendation of our landlords) for a large load of towels. For the past few months we've been using lavender dryer sheets from Mrs. Meyers Clean Day.
They're nice, and the lavender scent is a bonus, but when we pulled the towels out of the dryer last night (post tennis ball cycle) we were thrilled. The towels are as soft as they were when we used the dryer sheets and not even too static-y!
We're never looking back.
