I just got back from a week in Quebec and simply put my Raisin Bolide 31 in a tray and, while it was a little nerve wracking, she came through with flying colors! (I would probably not do this with my black box kelly, but the bolides I own are in togo or chevre so they are a little more scratch resistant). I do love the idea of the longchamp pliage! What a great idea!
