Four people, seven days.
Seven days of socks = 28 pair or 56 socks
Seven days of undies = 21 panties and/or boxer briefs
Seven days of bottoms = 24 jeans/sweats/yoga pants
Seven days of tops = 28 shirts + 10 sweatshirts/sweaters (roughly)
Seven days of pajamas = 10 pairs (roughly - if we get more than one night out of anyone's)
Seven days of towels = 8 towels (roughly - again, re-using before washing)
Seven days of washcloths/hand towels = 14 washcloths + 10-15 hand towels
Not even listed: jackets, linens, tablecloths, rugs, blankets, dog beds, clothes being laundered for garage sale, extra clothes used for accidents, spills, etc.
So, what have we learned here?
Seven days of laundry listed here = a clear, nauseating, painful understanding of why I am NEVER caught up on laundry. Ever.
