Hmmmm ... realizing as I cruised sewing box and basket images looking for the one above that I've not seeing anything that is quite like my own legged sewing basket (which I acquired at a antiques market many many years ago). The style of the legs places it in the fifties and the lidded wicker basket itself is a rather deep specimen with no sign of having originally had any internal trays or dividers. If it weren't for the wooden yoke with dowels for holding spools of thread which rests on a ledge inside, just below the lid I wouldn't have had any idea what it was for. Suppose I should bestir m'self to photograph it.
