From inner-tube swings in summer to ad-hoc snow sleds in winter, recycled tires are an indelible part of America’s childhood landscape. But why should kids hog all the fun? At My Sister’s Art, repurposed rubber gets the grownup treatment, metamorphosing from discarded bicycle inner tubes into eminently wearable statement jewelry. The fashion label also happens to be a sister act: Kathleen Nowak Tucci designs and creates the gallery-worthy pieces, while Margaret Nowak Dobos handles business and promotion.
