The sisters tend to horde materials, which provide the starting points for their ideas. On shelves, and in stacks of storage boxes, they keep samples of yarns, fabrics, and jersey swatches in every hue imaginable. “Our process is we start with the material and play with it, and while we’re doing that, we conceptualize the design,” says Vera. “It’s not like we design on paper. We let the material give us the information we need to decide where to go with a design; the qualities are inherent in the material we’re using.”
