Huh, I never thought about replacing them ….

• used to wash towels when they stink, and I was good about hanging them to dry so I didn’t have to wash them
• now I wash towels weekly, religiously
• beach towels never get replaced. They tend to be cheap scratchy towels anyway, rarely used and easily get lost, so keep them until I no longer have them. Actually these days they’re more likely used to dry my dogs feet
• bath towels … huh. Still on my first “real” family set and my kids are in college. They still work, but new ones are probably fluffier
