Designer of chic diaper bags, Petunia Pickle Bottom, also makes cosmetic cases, tote bags and iPhone cases. I’ve had my eye on the travel train case for awhile. The collection was also expanded to include infant carriers, layette items and swaddling blankets. Cake by Petunia is a higher end line of handbags (or secret diaper bags). Cute patterns – definitely better that the Winnie-the-Pooh versions from the days of yore.
