my recommendation is: rip an old bed sheet in 3" strips then get sturdy boxes from book or liquor stores. Pack boxes and tie them shut with the sheet strips in this manner: drape a strip over closed box, criss cross on the underside, bring up from bottom and tie tight and secure. Like wrapping a present with a ribbon. All 4 sides will be secured. Now boxes can be carried by the ties with 1 hand and should stay closed, even if tipped over. Save the $$$$ you would spend on totes for more sewing things!
