I need something big enough for dds' swimming stuff and that I could also use when I pick them up from school to throw art masterpieces, book bags, lunch boxes, Important Letters and unwanted jumpers and coats in. all of these got thrown on to the pavement in a fit of rage the other day when dds were nagging me to hold their hands. I thought a suitable bag might be easier to source than a spare set of hands... (and before you tell me they should carry it - I do insist they carry something but when it's at its worst it's still a right royal pita) I have in mind something open at the top, with shoulder straps, big enough to be able to rummage iykwim, preferably with an inside pocket for keys and purse, something a bit beach-bag-like I think. any ideas?
