Day 7: The Marauder’s Map Doctor’s Bag. Inspired by the Harry Potter’s books and movies, this bag features fabric depicting the Marauder’s Map. This bag’s design is based on Swoon Pattern’s Doctor’s Bag “Nora”. This is a classic handbag inspired by doctor bag purses of the past. True to the style, there is one large zippered pocket in the lining, dual handles and twist-lock flap closure.
