Picnic by Design is DIFFA National’s summer celebration that highlights design, food and fun for a worthy cause. Picnic by Design brings together designers, manufacturers and artists whose work is enjoyed, celebrated, and bid on by DIFFA supporters. Funds raised supports our grant making efforts to help nonprofit organizations across the country combating HIV/AIDS. Guests are invited to sip cocktails and wine while savoring picnic fare and bidding to win one-of-a-kind designer picnic baskets.
