Yep, you're doing your own laundry now, so you'll need somewhere to store your dirty clothes, and a way to transport them to the washing machine or launderette. Your best bet is a Laundry Bag With Handles (£7), which does double-duty.
Top tip: Keep a box of Dylon Colour Catchers (£3.50) close by, and you can wash your darks and lights together, to save on having to sort your laundry each wash day.
