From Berroco website:
Two distinct stories call for two distinct covers with a flip book design. In Norah’s “Eleanor’s search” story, web-like circles, patterned hexagons, striated yarns and lace are rich, warm and intriguing. On the flip side - In Norah’s “Urban Layers” story, bold simple pieces are layered in trios for maximal impact knit dressing.
