Sometimes good things come in doubles, as KAYU Design reminds me with designer Jamie Lim’s relocation to SF and today’s unveiling of company’s 1 handbag = 1 backpack program. Now that their bamboo sunglasses are helping provide finances for sight-restoring surgeries, a portion of proceeds from a new line of sustainable bags will benefit Awareness Cambodia’s efforts to provide school supplies and backbacks for Cambodian students. The Jen and Rachel bags (not a Friends re-run) are handwoven from straw and shells that are a by-product of the food industry–not a run-of-the-mill clutch.
